Further problem similar to Bug 465684, but this time for ProjectionViewer instead of SourceViewer. Doing: editor.showHighlightRangeOnly(true); editor.setHighlightRange(0, 0, true); When editor is an editor using a ProjectionViewer causes the following stack trace (this stack trace is from within a test I will submit soon): SegmentedModeTest.testShowNothingProjectionViewer testShowNothingProjectionViewer(org.eclipse.ui.editors.tests.SegmentedModeTest) org.eclipse.swt.SWTException: Failed to

I am working to see if I can find a fix for this. But in the meantime if anyone has any ideas I would be most welcome to them. I'll post my testcase soon too.
The editor in Comment 0 looks like this: public class TestSegmentedEditor extends TextEditor { public static final String EDITOR_ID= "org.eclipse.ui.editors.tests.segmentededitor"; protected ISourceViewer createSourceViewer(Composite parent, IVerticalRuler ruler, int styles) { fAnnotationAccess= getAnnotationAccess(); fOverviewRuler= createOverviewRuler(getSharedColors()); ISourceViewer viewer= new ProjectionViewer(parent, ruler, getOverviewRuler(), isOverviewRulerVisible(), styles); // ensure decoration support has been created and configured. getSourceViewerDecorationSupport(viewer); return viewer; } } i.e. a TextEditor with only ProjectionViewer instead of SourceViewer. I am trying to recreate a minimal test case, as the same problem occurs if I use CDT's CEditor (which uses a ProjectionViewer subclass too).

*** Bug 466063 has been marked as a duplicate of this bug. ***
(In reply to Jonah Graham from comment #2) Sorry for the long delay. I now added TextEditor#createSourceViewer with the code from comment 2 and could not reproduce the problem on master. Could you please give me detailed steps to reproduce the problem?
Waiting for response.
(In reply to Dani Megert from comment #6) > Waiting for response. Sorry for the delay. The attached gerrit sort of shows the problem. Since the test was written something has changed in how errors are logged. If you apply the gerrit, minus the code fix, and run it you should see a stack trace in the error log similar to Comment #0. At the moment our product has stopped using the ProjectionViewer in this way and I am failing to provide a better test case that demonstrates the problem.

Please set a target milestone again when you really plan to work on it.
This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. As such, we're closing this bug. If you have further information on the current state of the bug, please add it and reopen this bug. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant. -- The automated Eclipse Genie.
