Bug 151958 [Markers] Custom problem filter not updated
- create a minimal plugin with a plugin.xml like this: <?xml version="1.0" encoding="UTF-8"?> <?eclipse version="3.2"?> <plugin> <extension point="org.eclipse.ui.ide.markerSupport"> <problemFilter name="Problems" id="markererror.myPlugin.filterId" enabled="true" scope="ON_ANY_IN_SAME_CONTAINER"> <selectedType/> </problemFilter> </extension> </plugin> - start a runtime workbench, introduce a compile error in a Java class to get a problem marker. - in the problems view, disable the default filter, the filter "Problems" remains activated. - no markers are shown in the problem view. I debugged a little and found that the method MarkerFilter.setFocusResource() is only called for the default filter, not for the plugin-defined "Problems" filter: The latter filter is only contained in the field MarkerView.enabledFilters. The field MarkerView.markerFilters contains only the default filter.

categoriesToExpand.add(categories[0].getName());
						} else {
							Collection newCategories = new HashSet();
							for (int i = 0; i < categories.length; i++) {
								MarkerCategory category = categories[i];
								if (categoriesToExpand.contains(category
										.getName())) {
									getViewer().expandToLevel(category,
											AbstractTreeViewer.ALL_LEVELS);
									newCategories.add(category.getName());
								}
							}
							categoriesToExpand = newCategories;
						}
					}
				}
			}
			if (preservedSelection.size() > 0) {
				Collection newSelection = new ArrayList();
				ConcreteMarker[] markers = getCurrentMarkers().toArray();
				for (int i = 0; i < markers.length; i++) {
					Iterator preserved = preservedSelection.iterator();
					while (preserved.hasNext()) {
						MarkerDescriptor next = (MarkerDescriptor) preserved
								.next();
						if (next.isEquivalentTo(markers[i])) {
							newSelection.add(markers[i]);
							continue;
						}
