New Post: Sharing user control between views

Ok, I found the issue. MEF was loading the child VM when the Shell did an ImportMany but my child view was being bound to the ViewModel by a cal:Bind:Model as well. By removing the cal:Bind:Model which I didn't need everything seems to work as expected.

I'm just left with the issue that the Publish event has two subscribers both listening to the same message type - both Handle the message but I'd them to only do so if the message was for them.
