Actionscript 3 :: Bindable Property Change Event In Flex?

Sep 20, 2011

I'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?

Actionscript 3 :: Flex: Changing Control Properties Based On Contents Of A Databinding Event?

Sep 3, 2009

I'm trying to set up a form that presents a combobox when an ArrayCollection it's bound to has several items, and doesn't present one when it's empty or only has one item. I've tried doing this by creating this class, but unfortunately, the data provider I've bound to is never not empty at the time the setter executes.

Flex :: Parse Boolean Values In Strings For Use With Function.apply

Mar 13, 2010

I'm using String.split to parse a command line string into an array of strings. The result is then used to call a function using the Function.apply API.If apply(null, ["17"]) is called with this function:[code]does not work (expected output: false Boolean; actual output: true Boolean).Is there a way to make it recognize "true" and "false" (or anything else) as Boolean values, just like it does with numerical strings? Ideally "true" and "false" should also remain valid string values.

Flex :: Parse Boolean Values In Strings For Use With Function.apply?

May 5, 2003

I'm using String.split to parse a command line string into an array of strings. The result is then used to call a function using the Function.apply API.

If apply(null, ["17"]) is called with this function:

static function test(foo:int):void
{
trace(foo, typeof(foo));
}

it works as expected (output: 17 number).

However, calling apply(null, ["false"]) or apply(null, ["0"]) with this function:

static function test(foo:Boolean):void
{
trace(foo, typeof(foo));
}

does not work (expected output: false Boolean; actual output: true Boolean). Is there a way to make it recognize "true" and "false" (or anything else) as Boolean values, just like it does with numerical strings? "true" and "false" should also remain valid string values.

Flex :: Disable Databinding In MXML?

Aug 14, 2010

When the Flex SDK converts MXML to actionscript it generates a lot of databinding code. I don't want to bind a variable, for example if I know the variable will not change.

I can't seem to find a work around in Flex to disable the autogenerated databinding. Also, I was hoping this might also help with some of the runtime warnings thrown by databinding. To get around them, I sometimes use the following, which only throws syntax warnings (and don't appear in my console at runtime).

Syntax warning: Data binding will not be able to detect changes when using square bracket operator.

Actionscript 3 :: Not Understanding Basics Of Dynamic DataBinding (bindPropety) In Flex

Jun 6, 2010

I need to dynamically bind properties of components created at runtime. In this particular case please assume I need to use bindProperty. I don't quite understand why the following simplistic test is failing (see code). When I click the button, the label text does not change. I realize that there are simpler ways to go about this particular example using traditional non-dynamic binding, but I need to understand it in terms of using bindProperty.

Flex :: Combobox Not Updating With Bindable Data

My Combobox is not alway updating when I update the ArrayCollection.[code]...

the first time it updates the combobox fine and sometimes it works the 2nd, 3rd, etc time is might update the combo box. After it stops updating the combobox, it never does until I restart the app. I have verified that the ArrayCollection is updated via the debug data, it is just the combobox is not updating the display.

Flex :: Make A Wrapped Property Bindable?

May 20, 2011

I have Class1 with a read-only bindable property called age:

public class Class1 {
private var _age:int;
[Bindable(event="ageChanged"]

[Code]....

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 :: Flex Databinding With SelectedItem Property Of The Combobox Update Many Times

Jan 23, 2010

well, I have a combobox which I have bind his selectedItem property to a value object object, like this

<fx:Binding source="styles_cb.selectedItem.toString()" destination="_uniform.style"/>
<fx:Declarations>
<fx:XML id="config_xml" xmlns="" source="config.xml" />
<!-- Place non-visual elements (e.g., services, value objects) here -->
</fx:Declarations>

<mx:ComboBox x="66.15" y="63.85" editable="false" id="styles_cb" dataProvider="{config_xml.styles.style}" />

the value object is a custom class with some setters and getters, and I want to set a property based of the value of the selectedItem of the combo, so inside the value object I have something like this

[Bindable]
public function set style(value:String):void
{
_style = value;
trace(value);
}

my problem is that each time I change the combobox selection which in fact change the style property of the value object it does it 3 times, if I trace the value of the setter it actually do the trace 3 times, why?? how can I avoid this? I'm doing something wrong? or there is a better way to do it,

The problem is that my note corresponds mxml component, aka SingleNote component. There are four different cases when being, a. a note is updated from the server poll, in that case I want to singlenote to update the settings b. a note is added to the array from the server, in that case a new SingleNote needs to be created c. a SingleNote is added from client, in that case a Note is added to array, and sent back to server d. a SingleNote is change from client, in that case the Note is updated in the array and sent back to server

The properties are SingleNote(Width, X, Y, Text).
