I am using a custom modifier written guided by the example in http://

However, I am running mvvm and have an Annotations dependency property in my modifier.

However, when the Annotations property in my viewmodel is changed, the modifier does not redraw itself. I have to do something else, like switch over to another tab and then back again for the new annotations to appear.

Any ideas to how I can get the modifier to draw the new annotations?
