I'm creating a RCP Application. The eclipse form editor I use contains nested Composites (Sections etc.). Everything works fine if i do not create my form elements within such a sub composite (composite in composite). If I do so, I always get a org.eclipse.swt.SWTError: No more handles-Error when activating the editor by directly focusing such a form element (e.g. a text field). The error does not occur, if I click somewhere else in the editor window before.

Again:
1. I open the form editor
2. I activate a arbitrary view (e.g. outline or console)
3. I select a form element within a nested composite (= activate editor part again)

the following error occurs:

!MESSAGE Unhandled event loop exception

btw. I do not create any font, image or color object by myself.

help is really appreciated... I need those sub composites because they are contributed dynamically which is kind of a core functionality of the application.
