Hi there, I am struggling how to get access to the TopComponent of a file editor from MultidataDataObject.
I register a multi view editor for that object type and now have all the default cookies installed. However, I want to selette the source editor view on "Edit" acion and the visual view on "Open". So I did: public RosterDataObject(FileObject pf, MultiFileLoader loader) throws DataObjectExistsException, IOException { super(pf, loader); registerEditor("text/roster+xml", true); getCookieSet().add(new OpenCookie() { @Override public void open() { EditorCookie ec = getCookieSet().getCookie(EditorCookie.class); ((CloneableEditorSupport)ec). ec.open(); // TC is now supposed to be open and activated so we get it TopComponent activated = WindowManager.getDefault().getRegistry().getActivated(); MultiViewHandler mvh = MultiViews.findMultiViewHandler(activated); for (MultiViewPerspective perspective : mvh.getPerspectives()) { if (RosterVisualElement.ID.equals(perspective.preferredID())) { mvh.requestActive(perspective); } System.err.println(perspective); } } }); } However, the problem is that I open the editor twice and I am not sure the latter one is actually the active one.
