Outline view loses its context menu #2050

Closed lwrage closed 4 years ago

lwrage commented 4 years ago

Summary

Every once in a while the context menu in the outline view disappears. It appears again after a restart.

Steps to Reproduce

  1. Close all editors
  2. Open an AADL file, say P.aadl. -> The context menu in the outline view works.
  3. Open another AADL file, say Q.aadl, leaving P.aadl open. -> The context menu in the outline view works.
  4. Switch to the editor tab for P.aadl. -> The context menu does not appear any more.

Workaround

Close and reopen the text editor. Only the outline view for editor opened last will work.

Environment

I have a workspace that also exhibits this weird behavior Closing the outline and reopening it restores it

Interesting enough, this bug (in my case) is on a per-AADL package basis. In a given workspace, some packages have this bug, others do not.

Also, I do have occurrences of the menu being partially complete, the missing parts being resolute menus

right click leads to the following stack trace

This is not an OSATE issue as it happens for Xtend files, too.

Looks like it will be fixed as soon as we upgrade to the next eclipse version.
