Hi,
the method EModelService#findElement (all different signatures) does
only follow selected paths in the containment tree of the application
model. Generally it follows the children feature of MElementContainer
and some specialities such as the window trim. However, it does not find
a menu contained in a window. Would it make sense to change the
implementation to follow all containment features and exclude some
things if there is a specified search path?
Cheers
Jonas

I think if we expand the definition of findElement to include menus, then someone will want toolbars next, and pretty soon findElement is the equivalent of EcoreUtil.getAllContents().

Have you considered looking at an XPath-like query mechanism ke JXPath? I think Tom Schindl has a patch around to do some integration.

Brian.

Hi,

I see no reason why findElements should not be able to find all elements. I opened https://bugs.eclipse.org/bugs/show_bug.cgi?id=383403, lets see what Eric thinks.

Best regards, Lars
