Bug 482081

Description Pierre-Charles David 2015-11-13 03:34:46 EST

+++ This bug was initially created as a clone of Bug #482029 +++

See https://www.eclipse.org/forums/index.php/mv/msg/1072080/1714402/#msg_1714402 for reference.

I'll reproduce my response on the forum (this interpretation was confirmed by the original reporter):

This looks like an unintended side-effect of bug #456771 "Split UI 
contributions into optional plug-ins", where we moved most UI-related 
contributions (via the various plugin.xml) into new plug-ins. The idea 
was to allow people to consume the core of Sirius without having all the 
UI contributions enabled (all the views, perspectives, context menus etc.).

Apparently we were a little overzealous and moved the editor 
contribution too, even though its registration does not risk cluttering 
the UI and is not optional (like you discovered).

For the time being, a simple fix on you side would be to add an explicit 
dependency towards org.eclipse.sirius.diagram.ui.ext (and all the new 
*.ext plug-ins for that matter), and confirm if this fixes your issue. 
If it does, we'll reopen the ticket (or create a new one) to fix this 
and review the other changes made for #456771 for potential similar issues.

Note that this should not affect people who depend the Sirius features 
(as opposed to individual plug-ins), and the features in 3.0 include the 
new *.ext plug-ins.
