Build ID: 3.2.1 Steps To Reproduce: 1. Create new Logic diagram 2. Select logic diagram resource in Package or Project Explorer 3. In the top level menu go to Search->Text->Worksapce 4. In the search view click on the result corresponding to your logic diagram resource file Problem: there are exceptions logged in the errors view for a not found marker. Expected: no exceptions logged More information: GMF's MarkerNavigationService performs navigation to the marker as an async display message, while Eclipse's FileSearchPage expect this to run sequentially. Eclipse's FileSearchPage does the following: 1) creates marker 2) navigates to marker 3) deletes the marker Since navigation is performed in an async message the marker is removed from the MarkersSet before navigation is performed. There are 2 ways to fix this: 1) Navigate to marker sequentially 2) Check if the marker exists in the workspace before navigating to it. In this case navigation to the found text won't be avilable for diagram editors (which currently makes sense)
Created attachment 55321 [details] proposed patch Regarding 2 ways to fix the issue: the patch includes both ways: 1) Doesn't seem like navigation should be done as an async display message, any longer at least (Christian Damus agrees). 2) Before navigating to marker it should always be checked for existence - this just a good practice and, hence, wouldn't hurt to have this check.
Patch has been committed. Marking as fixed
