Flex :: Data Binding - Update Multiple Bindable Properties In Specific Order?
Apr 20, 2011I have a situation where I need to update a DropDownList's dataProvider and selectedItem in a specific order. See the following code ...
<s:DropDownList id="dropDownList"
dataProvider="{someDataProvider}"
selectedItem="{someSelectedItem}" />
In my case, some user interaction produces new values for the bindable variables "someDataProvider", and "someSelectedItem". However, when flex renders the DropDownList, the control's selected value is empty.
The reason for this is that the DropDownList's "selectedItem" property gets bound before the "dataProvider" property. The "dataProvider" needs to be bound first for "selectedItem" to be valid, this is because the new "selectedItem" points into the new "dataProvider".
what is the best practice for updating bindable properties in a specific order? I've come up with a few ways (e.g. using a valueCommit handler), but I wanted to see what the community had to say.
Actionscript 3 :: Bindable Getter Function Of Singleton Instance Never Being Called In A Data Binding Expression
Oct 26, 2011I have a singleton class that looks something roughly like this (only with more bindable public properties):
public class Session extends EventDispatcher
{
private var _Id:String;
private static const _instance:Session = new Session( SingletonLock );
private static const SESSID_CHANGED:String = 'SessionIdChanged';
[Code]...
The abnormal behavior I'm discovering is that the event listeners registered through registerOnSessionChange are indeed being called when the session Id changes, but the MXML data binding expression is not updating. I've tried all combinations of dispatching the event during the capture phase, and making it not cancelable, but to no avail. My understanding of [Bindable (event= ...)] is that the MXML should update the url string when the event specified is dispatched, so what am I doing wrong or misunderstanding?
Note: I realize there are lots of different ways of doing the singleton pattern in Actionscript, but unless the way I am doing it is actually causing my problem somehow,
Actionscript 3 :: Flex Data Binding Through A Refenced Property?
Jun 8, 2011class A: with a property "data:ArrayCollection". It's my data source (data provider) and has bitmaps.
class B: has an instance of A (called "Ainst") and calls the following method: C.init( Ainst.data). To pass the data provider to Object C.
class C: has a reference of the data provider "data" (because of "init" method). It shows the arrayCollection into Images as: Image.source = data.getItemAt(0).
But C never updates its images, that is, data binding doesn't work with this scheme. I've put [Bindable] meta-tag in all properties and even classes.

Actionscript :: Disable Warning (especially Binding Warnings) In Console In Flex (eclipse With Flex Plugin)?
Nov 10, 2010I did suppress warnings in flex compiler using "-show-binding-warnings=false". But what I am interested to achieve is to suppress run time warnings (especially binding warnings - since I am getting data in model mostly in XML structures and it is fine for me if its unable to bind to its nested child nodes) in console (I am working on flex on Eclipse with the flex plug in). Is there a way to achieve it?

Flex :: Compiler Shows Warnings : Data Binding Will Not Be Able To Detect Assignments To "company"?
Dec 11, 2009I have a custom ActionScript class:
package EntityClasses
{
import mx.collections.ArrayCollection;[code]....
And I want to bind these values to textBoxes, so that when user types information to the textBoxes it is populated in the class too. Is Flex 3 bidirectional so that marking the class with [Bindable] I can bind the values to a textbox for example?This is my mxml file in which I try to bind the class:
import mx.rpc.events.ResultEvent;
import EntityClasses.CompanyInfo;
[Bindable][code].....
The flex compiler shows me this kind of warnings: Data binding will not be able to detect assignments to "company".
Flex :: Watching A Bindable Property?

View 3 RepliesFlex :: Make A Wrapped Property Bindable?
May 20, 2011I have Class1 with a read-only bindable property called age:
public class Class1 {
private var _age:int;
[Bindable(event="ageChanged"]

Of course the [Bindable] tag there doesn't make sense. But how can I achieve the same effect?
I believe I can dispatch some sort of ageChanged event from Class2 up to Class1 and then have an event handler in Class1 dispatch another local ageChanged event to which I bind Class2's age property.
Actionscript 3 :: Bindable Property Change Event In Flex?
Sep 20, 2011I've got a component called Box.as that has following two properties, and have their getters & setters defined:
private var _busy:Boolean;
private var _errorMessage:String;
In MXML that uses this component I define it like this:
<components:Box skinClass="skins.components.BoxSkin"
busy="{presenter.boxBusy}"
errorMessage="{presenter.boxErrorMessage}"/>
Where presenter variable is defined here in MXML and a Presenter class has boxBusy and boxErrorMessage variables defined as bindable property change events:
[Bindable(event="propertyChange")]
function get boxBusy():Boolean;
function set boxBusy(value:Boolean):void;
[Code]....
PROBLEM is that whenever I change boxErrorMessage for the presenter, I see the affect in MXML but nothing happens at all when I change boxBusy. Is there something extra I need to do with boolean variable?
Flex :: Binding - Bind Property Of View To Property Of Class Using MATE?
Jan 9, 2011Lately i discovered MATE (for Flex development) and was wondering: how do i bind a property in a view (actually a navigatorcontent component) to another property in a class so that they stay in synchronization (meaning that whenever the property in the class changes the property in the view also changes).
So if we have a view called Target.mxml and a property targertProp how do we bind it to the class called SourceClass with property SourceProp?
Flex :: Flash Builder 'Access Of Undefined Property Bindable'
Jun 2, 2011I have inherited an Adobe AIR application, and am attempting to debug it through Flash Builder 4.5. Within Flash Builder, when I look at one of the MXML files, I see warnings for each use of the [Bindable] tag:[code]And there are no missing semi-colons on the lines preceding each warning as per the suggestion in this blog post.The project is configured to use Flex SDK 3.6.Additionally the file will not load in the designer, with this warning:Design mode: Error during component layout. Choose Design > Refresh to refresh design mode.At runtime I am seeing a blank window - which I assume is the result of the bindings not being triggered. Is this tag not available in Flex SDK 3.6?
View 1 RepliesFlex :: Unable To Bind Warning: Class Is Not An IEventDispatcher?
Apr 7, 2011I am getting the error: warning: unable to bind to property 'Description' on class 'Object' (class is not an IEventDispatcher)
this is only when the data is bound to a List as an ArrayList, though. I had it in a Datagrid before (just as an Array) and it did not cause any issue. I'm not expecting to be able to bind any data back to the class 'object' not even sure which object exactly it's referring to.
My list data-provider is an ArrayList.. populated by a result event from an SQL query contained in another class:
private function loadDayComplete():void
{
var Meals:Array = _day.MealResults;
[Code].....
The day class I have is a data holder to get all the data (from several tables) for a 24 hour span.. I have classes for each individual datatype for editing them. But I'm not sure do I even need to worry about the warning if I don't plan on editing the values? it completely spams the console though whenever I touch anything, so I really would like to get rid of it. I tried an object proxy as I saw described elsewhere but nothing changed. The text is in label fields right now anyway, which can't even be edited.

Flex :: Unable To Bind The SelectedIndex Of A DropDownList To The SelectedIndex Member Of A Bindable Class
Feb 8, 2012I am unable to bind the selectedIndex public property of a spark DropDownList to it's original source in the view's presentation model.
For the purposes of replicating this issue with as few lines as possible I have two views, and one presentation model. The code follows.
Main.mxml
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"

Debugging the application I find that selectedIndex in the presentation model always remains at the default value assigned regardless of which item I selected from the DropDownList. For the sample code above this is -1.How can I bind the selectedIndex in the presentation model such that it is updated appropriately when the selected item DropDownList changes?

View 1 RepliesFlex :: Data Binding Re-bind When Data Model Not Change, Possible?
Nov 4, 2011If user change the value of the TextInput, then click refresh button to retrieve the data model from backend again, the GUI value will not change back. Re-binding not happen, Since the value of data model not changed, no propertyChanged event fired.In this case, I must Programmatically set the model value to the GUI after data refreshing done.I know bi-directional binding can solve this problem(when user change value on GUI, set the new value to data model immediately). But sometimes I cannot use bi-directional binding, for example, the data model is a int, but user input a non-int value, I cannot set the value to data model. So the value in data model do not change, when refresh data, rebinding still not happen.
This will make the data binding useless. How to resolve this?I put pseudo-code here for now, I will put real code later:1. retrieve a data model from server, via blazeds or something else.2. bind the model to a TextInput on GUI.3. user change the TextInput text.4. User click a refresh button, triger retrieve the model value again.5. Now since the model value do not change, no PropertyChanged event fired.6. GUI value still is the user's input, not the value from the model. can clear the model value before set the velue back, make re-binding happen.(but sometimes you do not know how to clean the model value, take int for example, you may do not know the original value and happen set the same value). Or I can manually set the model value to GUI. But both are not good looking.
Flex :: Binding To An Specific Property Of Objects In An Array?
Jul 22, 2009I am using Flex to create a small form. All I have at the moment is a List component, that I want to populate with a list of font names.I am getting the fonts using Font.enumerateFonts(true);. This returns an array of flash.text.Font objects.
The Font objects have a fontName property that is a String of that fonts name.My problem is that I can't figure out how to bind the List's dataProvider to the fontName property of each of the Font objects in the Array.Is there a way to do this just with binding? and not creating a new array of Strings by looping through the Font objects?
Flex :: AS3 - Creating Dynamic Property And Then Binding Control To It
May 5, 2010I am trying to:
1) create a dynamic property
2) bind that property to a label
This works great for "sealed properties", but for dynamic properties there doesn't appear to be any event triggered. Are dynamic properties implicityly not bindable?
var myObj:MyType = new MyType(); // MyType is dynamic
myObj["myDynamicPropertyName"] = "initialized";
BindingUtils.bindProperty(myLabel, "data", myObj, repeatedLabel.name);
// myLabel now displays "initialized"
myObj["myDynamicPropertyName"] = "changed";
// myLabel still displays "initialized", it should say "changed" !!!
Flex :: Binding On Width Property Using Percentages In MXML?
Jun 2, 2010Is it possible to set a percentage value for the width property of an UIComponent defined in MXML using data binding?
What I try to achieve is something like this (which doesn't work):
<s:Button width="{buttonWidth}%"/>
I know that using percentage for width or height properties in MXML is kind of a hack in the Flex SDK, since they're supposed to accept numerical values only, but since percentWidth and percentHeight aren't available in MXML, I'm pretty stuck =/
I would really like to avoid using code to do such a simple thing, in order to keep my code as clear and readable as posible.
Flex :: Conditional Data Binding?
Oct 8, 2009first one shows playheadtime of videodisplay and another is also used for same purpose. the difference is that when we are in add mode(decided from a flag variable) both should show current playheadtime using binding. but when we are in edit mode(again decided from flag) the latter label should remain static, to be more specific, the value retrived from database.how can I do that using actionscript. I tried ChangeWathcer but I found it a bit tricky. Is there any other simpler way or am I missing something. following is my code.

Flex :: Data Binding Not Working
May 3, 2010I'm having some troubles with binding data. I have an application that contains a viewstack of components. Let's say I have comp1, comp2 and comp3 inside the viewstack. Each component, has its own data class --> comp1Data.as, comp2Data.as and comp3Data.as. All values in each component are binded to the corresponding data in it's data object.
A click in a control in comp1 leads to comp3, the same goes for comp2. Clicking a control in comp2 leads to comp3. When going from comp1 to comp3, comp3Data.as is initialized and and comp3 displays the binded values. When going from comp2 to comp3, comp3Data.as is also initialized but the binded values are not displayed...

Flex :: Data Binding With A Value Inside A Component ?
Mar 30, 2010I'm using Flex with Cairngorm framework.I have a custom component which I create like this:
<components:FriendSearchPaginator id="searchResultsPaginator"
paginationElement="{_model.findFriendsPaginationElement}"
visible="{_model.friendsSearchResultsPaginatorVisible}" />
Where the findFriendsPaginationElement is inside the model locator:
public var
[Bindable]
findFriendsPaginationElement:PaginationElement = new PaginationElement();
Inside the custom component I have button that uses a property of findFriendsPaginationElement object:
<s:Button id="previousButton"
label=" prev "
click="paginateSearchResults(false)"
enabled="{_model.findFriendsPaginationElement.more_previous}"/>
But I get a warning from Flex that the binding wouldn't work that way and it doesn't. It works the first time I load up the component but every time I change findFriendsPaginationElement it doesn't reflect on the component. Do you know how I can go about doing this? (making changing a value in the binding variable changes the status of an element inside a component?)
Flex :: Two Way Data Binding In AS Causes Stack Overflow
Jul 21, 2010I'm binding two AutoCompleteModified objects to one another; meaning you type in one and it selects the correct object in the other. It works fine when I define it in MXML: However, a user can add a new row to a Grid and then I set up the binding and objects via actionscript and it gives an 'undefined' error:
ChangeWatcher line 427/wrapHandler.
var innerHBox:HBox = new HBox();
var dtc_acm:AutoCompleteModified = new AutoCompleteModified();
dtc_acm.dataProvider = data2;
dtc_acm.labelField = 'id';
var cp_acm:AutoCompleteModified = new AutoCompleteModified();

If I only keep it 1-way binding then it works fine. But both throw this error. Is there something about not only doing it 2-way in actionscript, but adding components that aren't on the stage yet?
