I have now also, changed the event type from Object to Event, in the
cairngormEventDispatcher call. So the code looks like this:
public function updateSelectedShip( event : Event ) : void
{
selectedShip = event.target.selectedShip;
CairngormEventDispatcher.getInstance().dispatchEvent( new
CairngormEvent( SELECT_EVENT ) );
}
Also I debugged nearly every line of code trying to discern whats
going on, and in the event.target I found an attribute called
selectedItem, which I did not create. So I dont know if thats being
setup somehow automatically or not.
If I set in the select event "model.selectedShip =
event.target.selectedItem"
the thing changes the grids selectedShip shipVO object to what the new
selection is.
However the MODEL is still not being updated. I dont get it.
I can update the workflow state on the model by clicking buttons, I
can adjust the various arrays that are being stored on the model, but
I cannot set this one shipVO object equal to what is currently
selected in the grid.
Someone please help!!!
