Workflow 4.5 with custom activities

Question

I created a number of custom activities in a rehosted designer.  What I have seen is that when I add another activity my activity  constructor is called again.  In my activity constructor I set a view model to associate a dialog and this causes
the view model to not match the model item associated with the Activities.
The revelant code is:
public InstructionDesigner()
InitializeComponent();
infoDialogViewModel = new InfoDialogViewModel();
Where the designer constructor creates the view model but being called twice when I add a new activity.  If I add another activity beyond the second activity I am only constructing one.  It looks like when I add the second activity it is reconstruction
the original activity and putting a sequence activity around it.
How should I handle this or is there a work around so I can attach a viewmodel to a specific instance of the activity.
