Re: DockableFrameFocusChanged

I atteched a copy of the SDK example "DochableDialogs". The only difference is in file ExternalCommandRegisterPage.cs, 53:

         ThisApplication.thisApp.GetMainWindow().SetInitialDockingParameters(dlg.FloatLeft, dlg.FloatRight, dlg.FloatTop, dlg.FloatBottom, dlg.DockPosition, dlg.TargetGuid);
         try
         {
           ThisApplication.thisApp.RegisterDockableWindow(commandData.Application, dlg.MainPageGuid);            commandData.Application.DockableFrameFocusChanged += new EventHandler<Autodesk.Revit.UI.Events.DockableFrameFocusChangedEventArgs>((sender, e) =>
            {
               TaskDialog.Show("Event", "Raised!");
            });
         }
         catch (Exception ex)
         {
            TaskDialog.Show(Globals.ApplicationName, ex.Message);
         }

In order to reproduce the test Case you simply have to follow the steps described in the readme file:

Instructions: Build and install the addin, and start Revit.  Before opening a document, select the “Register” ribbon button in the “DockableDialogs” ribbon tab to launch the registration dialog.  Select a docking style (bottom, top, tabbed, floating, etc…).  After opening a document, note the docked-modeless API window in the UI.  The “Hide” and “Show” buttons in the DockableDialogs ribbon can hide and show the dialog without destroying it.

The expected behaviour is to show a tast dialog each time the DockablePane lose Focus, what is never happening.

please reply in case you need more info.
