Add-in Button OnUpdate() is not Called

Question

Hello, I created a simple add-in Button that opens a mxd document. The button uses the OnUpdate() event to check when the document is finished opening and then runs some additional code. The Button worked as expected until I moved it's Config.esriaddinx entry from to a (drop-down menu). Since moving the Button to a drop-down menu, the OnUpdate() function does not get called. However, the OnUpdate() function is eventually called when I click the drop down menu that contains the button. Is this expected behavior for the OnUpdate() event? I'd like to know why the Button's OnUpdate() behavior is different between toolbar UI styles. Thanks, Josh

This seems to be a bug, so I've opted for a workaround.  I was able to get the behavior I needed by using ESRI.ArcGIS.ArcMapUI.IDocumentEvents_OpenDocumentEventHandler.  Still, I prefer the OnUpdate() method since it was cleaner.  Thanks for the help.

The menu does not have an "ondemand" property. The menu is basically just xml tags that ArcMap uses to organize add-in controls on the toolbar. As far as I know the menu is not an object that can be extended or accessed with ArcObjects. Here is a generic example of my Config.esriaddinx code:

This makes me wonder if the menu's OnDemand also needs to be set.
