Toolbar Contribution [message #782099]

I am trying to get a toolbar contribution over the model service. The id is defined in the Application.e4xmi. An handled item is also defined. The part let inject the MApplication and the EModelService.

But when I try to get the contribution or the item I get always null.

final MUIElement contribution = modelService.find("toolbar-contribution-id", application);
final MUIElement item = modelService.find("toolbar-contribution-item-id", application);

modelService and application are not null...

any hints?
Thx Beat

EModelService's searches are pretty much restricted to looking at contained children. An MWindow or MPart's toolbar isn't actually considered to be a child of the element but an attribute. The comment is a bit confusing.

In my usage, I've usually wanted to get a tool item relative to either the active window's toolbar or the active part's toolbar, or the toolbar for a particular part, and so been able to avoid the recursive descent of EModelService#find() and friends.

Well IMHO this is a bug in EModelService then. They should simply use an
TreeIterator to find all "children" of an element.
