Bug 300032 [Markers] NPE in MarkerFieldFilterGroup.selectByScope
I20100115-1100 I had a Java editor open and dirty. The Problems view was NOT visible (topmost in that view stack was Progress). I pressed 'Alt+Shift+W, P, Return' to reveal the file in the Package Explorer. The stored file had no compile problems, but the the working copy in the editor had a problem which I fixed shortly before I started the Show In action. java.lang.NullPointerException at org.eclipse.ui.internal.views.markers.MarkerFieldFilterGroup.selectByScope(MarkerFieldFilterGroup.java:693) at org.eclipse.ui.internal.views.markers.MarkerContentGenerator.select(MarkerContentGenerator.java:781) at org.eclipse.ui.internal.views.markers.MarkerContentGenerator.internalGatherMarkers(MarkerContentGenerator.java:1073) at org.eclipse.ui.internal.views.markers.MarkerContentGenerator.gatherMarkers(MarkerContentGenerator.java:1013) at org.eclipse.ui.internal.views.markers.MarkerContentGenerator.generateMarkerEntries(MarkerContentGenerator.java:991) at org.eclipse.ui.internal.views.markers.MarkerUpdateJob.clean(MarkerUpdateJob.java:117) at org.eclipse.ui.internal.views.markers.MarkerUpdateJob.buildMarkers(MarkerUpdateJob.java:77) at org.eclipse.ui.internal.views.markers.MarkerUpdateJob.run(MarkerUpdateJob.java:57) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:55)
