I have an application that contains a datagrid and a custom
component. I want to notify the custom component that the user has
changed rows in the grid. The application has some associated
ActionScript. In the ActionScript, I setup the listener as follows:
this.addEventListener("rowChange", customComponent);
When the user does a mouseUp on the datagrid, I have it do this:
function broadcastChange()
{
dispatchEvent({type: "rowChange"});
}
And, in the custom component, I have this function:
function rowChange() : Void
{
if (dataObject.hasNote() == true)
detailViewNoteButton.enabled = true;
else
detailViewNoteButton.enabled = false;
}
The problem is that, while the dispatchEvent is called correctly,
the custom component's rowChange function never gets called. Any
ideas why? The custom component is declared as follows in the
<mx:Application> MXML:
<mx:Canvas id="topCanvas" width="100%" height="55%">
<CustomComponent id="customComponent"
dataObject="{grid.selectedItem}"
</mx:Canvas>
It works fine if I make a local object the object listener instead
of the custom component as in
var listenerObject = new Object();
listenerObject.rowChange = function(event)
{
// handle event
}
this.addEventListener("rowChange", listenerObject);
It's almost like the addEventListener doesn't know about the
customComponent instance...
Thanks,
