    Resolution: Invalid
      Assignee: Howard M. Lewis Ship

I'm not going to introduce the capability you suggest expressly because it is dependent upon internal implementation details of the outer component; the ids of the nested components that are incorporated into the method names or annotation values.  That is a bad idea, since it ties down the implementation of the outer component in an unacceptable way.

> I have an address component addcomp.tml with has 2 submit buttons with  t:id="add" and t:id"remove".
> I add this component (with t:id=" addcomp" ) to my Page address.tml .
> Now the page should handle the following events (pseude code)
> @Event(component=" addcomp.add")  onSelectedFromAdd() and 
> @Event(component=" addcomp.remove")   onSelectedFromRemove() .
> But the tap5 gives me only the change to hande 
> @Event(component=" addcomp")  onSelectedFromAddcomp ()
> in the page(container) code -I can get chance to handle the add and remove event individually.
> My Proposual:
> Allow something like:
> @Event(component=" addcomp.add")  onSelectedFromAddcomp_Add() and 
> @Event(component=" addcomp.remove")   onSelectedFrom Addcomp_Remove() .
> With this approach you have to know internalsof components(the Is's)- but this is a documentation issue.
> You just have to state "this component produces "add" and "remove" select-events".
> This may be done by @Annotations to have a formal documentatuion of these generated events.
> These may be used (to generate code) to call the appropriate callback-functions in the containers.
> Another solution may be to allow to alloe the sumit component to specify the Event Type generated.
> These different Evnttypes may afterwards be handlet by the container.
> This may be not a really bug (there are workarounds) but this workarounds may produce awksome code.
> I would like to have an "Event-Bubble solution " for this issue.
> But I may be wrong...
> Can you tell me how to solve my problem?
