Bug 47207 call hierarchy: Enablement of "Search Scope" item on view menu is wrong [call hierarchy]
At least on Windows NT/2000 this item is shown as disabled until the user clicks it it which case the submenu opens. I have been looking into this problem but without any results so far. Any suggestions are welcome.
org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/callhierarchy/SearchScopeActionGroup.java
private IWorkingSet mWorkingSet;
        public SearchScopeWorkingSetAction(IWorkingSet workingSet) {
            super(workingSet.getName());
            setToolTipText(CallHierarchyMessages.getString("SearchScopeActionGroup.workingset.tooltip")); 
            WorkbenchHelp.setHelp(this, IJavaHelpContextIds.CALL_HIERARCHY_SEARCH_SCOPE_ACTION);
            this.mWorkingSet = workingSet;
        }
        public IJavaSearchScope getSearchScope() {
            return SearchEngine.createJavaSearchScope(getJavaElements(
                    mWorkingSet.getElements()));
        }
        /**
         *
         */
        public IWorkingSet getWorkingSet() {
            return mWorkingSet;
        }
        /**
         * @param adaptables
         * @return IResource[]
         */
        private IJavaElement[] getJavaElements(IAdaptable[] adaptables) {
            Collection result = new ArrayList();
            for (int i = 0; i < adaptables.length; i++) {
                IJavaElement element = (IJavaElement) adaptables[i].getAdapter(IJavaElement.class);
