Apply Authorization Rules Problem

I'm getting  null value exception at the line:

this.DetailsView1.Rows[
      this.DetailsView1.Rows.Count - 1].Visible =
      Client.CanEditObject();

Value cannot be null  Parameter name: container

The Client object definitely exists and I reset the CanEditObject to just return true, and finally removed Client.CanEditObject and set Visible = true

Nothing seems to work.  Ideas?

This could be a silly question, but have you checked everything on the left hand side of the equals sign to make sure that nothing is returning a null?

Sheesh!  DetailsView.Rows[] is null. 
On the form, I can refresh the control and it detects the fields in the business object.  That is what Rows refers to, right?  So why is it unable to count Rows?

Is this related to the csla DataSource problem discussed here?
http://forums.lhotka.net/forums/thread/2093.aspx.  I thought I'd found a work around, and at least the control displays.

Thanks for the suggestion.  Now I know what is wrong, but I have absolutely no idea of how to fix this.
