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
public SelectWorkingSetAction() {
            super(CallHierarchyMessages.getString("SearchScopeActionGroup.workingset.select.text")); 
            setToolTipText(CallHierarchyMessages.getString("SearchScopeActionGroup.workingset.select.tooltip")); 
            WorkbenchHelp.setHelp(this, IJavaHelpContextIds.CALL_HIERARCHY_SEARCH_SCOPE_ACTION);
        }

        public void run() {
            IWorkingSetManager workingSetManager = getWorkingSetManager();
            IWorkingSetSelectionDialog dialog = workingSetManager.createWorkingSetSelectionDialog(PlatformUI.getWorkbench()
                                                                                                            .getActiveWorkbenchWindow()
                                                                                                            .getShell(),
                    false);
            IWorkingSet workingSet = getActiveWorkingSet();
            if (workingSet != null) {
                dialog.setSelection(new IWorkingSet[] { workingSet });
            }
            if (dialog.open() == Window.OK) {
                IWorkingSet[] result = dialog.getSelection();
                if ((result != null) && (result.length > 0)) {
                    setActiveWorkingSet(result[0]);
                    workingSetManager.addRecentWorkingSet(result[0]);
                } else {
                    setActiveWorkingSet(null);
                }
            }
        }
    }
