Ok, I found one additional piece of info that when I sent this I
thought was not relevant. In my main.mxml, my component.mxml is
actually an itemrenderer. So the code for it would be:
<mx:itemRenderer>
<mx:Component>
<view:fileActions DownloadResizeEvent="handler_resize(event)"/>
</mx:Component>
</mx:itemRenderer>
Instead of :
<view:fileActions DownloadResizeEvent="handler_resize(event)"/>
Now the reason this seems relevant is because if I comment out the
item renderer code, and place just a single instance of my
component.mxml in my main.mxml - it works fine. No more errors.
So to sum up.... when a custom component that dispatches a custom
event is placed within the above mxml code - it will not see the
defined event handler.
ideas?
