Hi Bill,

I have a feeling that the other views you need to touch are not InitialSelectedAliases of their respective bizobjs.

In a case like this I would create a separate bizobj for any view that needs updating.

Then you can cascade changes by using the bizobj's postsavehooks or tie them to events on the form.

If there is a predetermined sequence of actions that must be taken upon the firing of a specific event, I suggest you follow Jim Weil's advice, and create an event object.

Good luck!

Alex
