Can't Set Action on menu item in NB6 Desktop Application

I've been playing with the new Java Desktop Application framework. The new support for Actions on menu items and buttons looks great. But I can't get it to work. After generating a simple desktop application, I add a menu item. When I right-click on the menu item, the context menu doesn't contain the Set Item menu item. If I select one of the menu items created with the project, e.q. the Help menu's About item, then the Set Action item is on the context menu.

In addition, if I look at the action property for the About or Exit items generated with the project, they have a Default Editor installed. If I look at the properties for a menu item I add, there is no default editor for the action property, only Component Chooser, Value from existing component, and Custom code.

Am I missing something, or is this a bug?

Thanks
