[flexcoders] Re: MXML Component and binding with a setter

[biosmonkey]

I don't know if I can post source, but let me see...
Here is source for a sample app:


<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml";
layout="vertical" xmlns:ns1="*" horizontalAlign="left">
<mx:Script>
     <![CDATA[
         import mx.collections.ArrayCollection;
         [Bindable] public var myAC:ArrayCollection=new
ArrayCollection();
         [Bindable] public var myInt:int=0;
     ]]>
</mx:Script>
     <mx:DataGrid dataProvider="{myAC}">
         <mx:columns>
             <mx:DataGridColumn headerText="Data" dataField="data"/>
         </mx:columns>
     </mx:DataGrid>
     <ns1:MyComp dataInput="{myAC}" dataIntInput="{myInt}" />
     <mx:Button label="Add Item" click="{myAC.addItem({data:123})}"/>
     <mx:Button label="Increment Int" click="{myInt++}"/>
</mx:Application>

and here is source for the component "MyComp.mxml":

<?xml version="1.0" encoding="utf-8"?>
<mx:HBox xmlns:mx="http://www.adobe.com/2006/mxml";>
     <mx:Script>
         <![CDATA[
             import mx.collections.ArrayCollection;
             import mx.controls.Alert;
             public function set dataInput(data:ArrayCollection):void
             {
                 Alert.show("Setting dataInput="+data);
             }
             public function set dataIntInput(data:int):void
             {
                 Alert.show("Setting int="+data);
             }
         ]]>
     </mx:Script>
</mx:HBox>


All I am doing here is showing a datagrid that is bound to an
arraycollection, along with a custom component with a setter function
that is also bound to the same a.c.

If you click the button to add an item, it shows in the datagrid, which
means it is detecting the change to the arraycollection as I would
expect.  However, the setter in the custom comp does not fire.

As a test, I also added a simple int, which IS being detected by a
different setter.
