registry for event from cid-implementating component failed

hi,

I have a problem with the following scenario:

- I have a component Main, component interface definitions (cid´s) L and MENU

- component M1 and L1 implement the cid

now my problem:

Main embedds the interface view of cid L (in my case the component L1 at runtime) and L1 embedds the interface view of cid Menu (M1 at runtime). both embedding of course in a view container.

In M1 I got a tree ui-element and when a leaf in the tree is clicked a event in M1 is fired. This event is defined in the cid Menu and Main has registered for it with an eventhandler method.

when I start my application the event is fired in M1 but Main-component didn´t execute its eventhandler method for this event. what could be the reason?

has anyone an idea?
