Dynamic View Menu [message #792691]

I'm trying to offer a view menu for a part which allows to save the current configuration of the part under a given name. Later, I'd like to be able to recall that configuration. The view menu looks like this:

Save...
-----------
Load > Config 1
       Config 2
       Config 3

I'm building the Load submenu from the configurations I get from a backend service. This works when I'm initially building the part, but when I change the part menu from the Save... DirectMenuItem handler, the Load submenu is not properly rebuilt.
I've tracked the problem down to the this code in StackRenderer:

		Object obj = menuModel.getWidget();
		if (obj instanceof Menu) {
			menu = (Menu) obj;
		}
		if (menu == null || menu.isDisposed()) {
                   ...build the menu from the model

, so the menu is never rebuilt. As I understand the "modeled workbench" concept, it should be sufficient to update the model, correct?

Any suggestions are welcome.

Yes - all model changes should be reflected in the UI.

Would you be able to make a small test part and submit a bug report?
