Unable To Bind To Property Of Custom Component
Feb 25, 2010
Can't seem to bind to data from within a custom component. I've tried BindUtilis and {} but can't seem to fathom it out. Here's what I've got:
I have a class DataModel which has been made bindable
Within Mainn.mxml I have two components: DataGrid (used for testing) & CustomComponent (which extends Canvas)
When the data within DataModel.somelist is updated the DataGrid reflects the changes but the CustomComponent doesn't appear to.
I was expecting to see the trace (CustomComponent.dataProvider) fired whenever this._dataModel.itemList is changed. [code]...

Is is possible to bind class properties to mxml components ? E.g.: I have a class A.as with a String property nameValue. What I want to achieve is always having the latest value of a mx:Text component in nameValue.

My question is if i can define custom style names like dividerRightColor and if so, how can i use that value inside my MXML Component? I have seen examples of using them inside Pure AS components.

Lately 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?

I have a custom Flex 4+ component that I am trying to make and have the skin be aware of changes to a custom property. This property will determine the graphic on the button (and some other visual changes) but the data will change constantly as it will be updated by a timer.
I've looked at untold examples and still seem unable to get the syntax correct or discover how things should be separated. I've looked at overriding commitProperties and the PropertyChangeEvent without success. So I have two questions.
1) How can I get a skin to be notified of a bound property when it changes?
2) If the data for a bound property of the component is an object, will binding work properly if a property of the object changes (or would it be better to pass each property separately)?

I would like to know if it is the same to assign properties to my custom component in its own class, or from the parent document. Here I assign the property bottom in my custom component class:
<?xml version="1.0"?>
<mx:LinkButton bottom="20" >
<mx:Script>
Here I assign the property bottom when I use the component in my main MXML file
<myComp:Brick bottom="10"/>

I have written a piece of code where I have created a custom class containing some of my custom properties.I have used multiple instances of this custom class in my main class and added it to a container.Now I need to access one of my custom property in the main class through container.getChildByName()."custom property", but I am not able to access my custom property using this.I get an error saying
Access of possibly undefined property orientation(this is my custom property) through a reference with static type ..name of my main class.
Is there no way that can i access custom property of components through the getchildbyname method of the parent container ??

Here the method clientMonitor() is called on creationcomplete() from the main application.
I am not able to bind the Bindable variable dbl to my textInput. Using the debugger, I am able to see that the result is assigned successfully to variable dbl, but it is not able to bind it to the text of view1. I see a NaN displayed in the text of view1.

I 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.

I created a custom MXML component, TurboContent, that extends the NavigatorContent class:
<s:NavigatorContent xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx">
[Code].....
In this case, the 'myButton' component never shows up, but all the elements of the base component do (3 buttons and a datagrid).

I have a custom component based on mx:ComboBox. Within it I connect to an HTTPService (the url is passed as a paramter) and bind the combobox. Parameters to be sent to the HTTPService are passed to the component. This is working fine. But I want to modify it to make it re-usable with other HTTP service URLs, which return the XML in a different format.
My challenge is how can I bind a custom component to a node dynamically at runtime?[code]...

I've developed a component which is a combination of a few items (canvas, labels, etc...) but when I try to bind it to a variable such as: {stationXML.getItemAt(1).AAA.@value}, it doesnt work. Before I combined all the items in a component, they were all in the main MXML file at which time they worked. Not sure if it matters, but the "stationXML" arraycollection variable is declared inside the file "Station.as".

I 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"
[code]...
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?

Does there exist a Flex view component that you could just pass it a custom object with all public fields/properties that it could reflect over and produce a basic UI view using flex components. Is it possible to use something like the Spark DataGrid with one item laid out vertically. It would only have to support:

i am a bit embarassed to ask this, but i do this so much i have to ask. Occasionally, i need to pass/handle custom events on the fly. Rather than creating a whole custom event class, i will just do something like
Code:
myObject.dispatchEvent(new Event('thisCustomEvent'));
//and then handle it later

I couldn't work it out yet...
package components {
public class templateSelection extends VBox {
static public var tempSelectionBag:Dictionary;

I want to have a custom class tempSelection with a Dictionary as a public accessable property of that class. If I use this code, the compiler tells me:
1046: Typ wurde nicht gefunden oder war keine Kompilierungszeit- onstante:Dictionary
Which translates to:
Type was not found or was not a compile-time constant: Dictionary
