How can I programmatically activate a view's tab?

Code similar to the below works for other CAL region managers, but does not work for XamDock

IRegion region = regionManager.Regions[RegionNames.MainRegion]; 
object view = region.GetView("MyView"); 
region.Activate(view);

Any suggestions?

I know this is a long time from your original post, but I discovered switching to the tab is accomplished by changing focus to an item in that view.

So after region.activate I've been adding something like:

view.FocusFirstItem();

That code sets the appropriate focus. This is filtering though my view model but it works pretty well.
