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.

MarkerFilter[] newMarkers = new MarkerFilter[initialFilters.length];
		for (int i = 0; i < initialFilters.length; i++) {
			MarkerFilter newFilter;
			try {
				newFilter = initialFilters[i].makeClone();
			} catch (CloneNotSupportedException exception) {
				ErrorDialog.openError(getShell(),
						MarkerMessages.MarkerFilterDialog_errorTitle,
						MarkerMessages.MarkerFilterDialog_failedFilterMessage,
						Util.errorStatus(exception));
				return;
			}
			newMarkers[i] = newFilter;
		}
		filters = newMarkers;
