Thanks Tim for your answer but my problem come from the way i can
gather all the data from differents views in a sole custom event. I
agree with you for the rest.
My button which trigger the event is in a separate view than the video
display i want to take a snapshot. Of course here the problem is
simple but i want to generalize it.
I think that i was complicating the problem by trying to lead the
event to the view that have the videodisplay which then send the custo
event to the command.
A better way is to simply confide in the parent container of the two
view to send itself the custom event to the command cause it have
access to the data all the view.
<!-- my composite view -->
<mx:VBox ...>
<mx:Script>
<![CDATA[
private function handleTakeASnapshot(event:snapshotOrderEvent):void
{
// Trigger the final event to the command
var snapshotVo:SnapshotVO = new SnapshotVO();
snapshotVo.image = view1.getSnapshot();
var doSnapshotEvent:DoSnapshotEvent = new DoSnapshotEvent(
snapshotVo );
CairngormEventDispatcher.getInstance().dispatchEvent(
doSnapshotEvent );
}
]]>
</mx:Script>
<view:view1 id="view1" />
<view:view1 id="view2" myInititialEvent="handleTakeASnapshot(event)" />
</mx:VBox>
It 's correct and clean like that?. If i'm wrong tell me cause i'm a
newbie with flex and cairngorm and i want to get the good reflex.
Thanks again
