MaskedEditValidator not working in MultiView

Hello, everyone!

This seems like such a major bug, I am thinking I must be doing something wrong, but I can't figure out what.  I am trying to use some controls with MaskedEditExtenders and MaskedEditValidators inside a MultiView.   In this example the validator is in view A2.  I am OK going from A1 to  A2 and back to A1.  However, the second time I try to switch to A2 I get this error:

Microsoft JScript runtime error: Sys.ArgumentNullException: Value cannot be null.
Parameter name: element

If I remove the MaskedEditValidator I don't get this error.  I am using the latest version of the Ajax Controls Toolkit.  Any ideas?

    Protected Sub btnPrev_Click(ByVal sender As Object, ByVal e As System.EventArgs)
        If MultiView1.ActiveViewIndex = 0 Then
            MultiView1.ActiveViewIndex = MultiView1.Views.Count - 1
        Else
            MultiView1.ActiveViewIndex -= 1
        End If
    End Sub
 
    Protected Sub btnNext_Click(ByVal sender As Object, ByVal e As System.EventArgs)
        If MultiView1.ActiveViewIndex = MultiView1.Views.Count - 1 Then
            MultiView1.ActiveViewIndex = 0
        Else
            MultiView1.ActiveViewIndex += 1
        End If
    End Sub

Sophia,
This error will only happen in debug mode
stop the debugger and test the script in a browser, you should not see this error
I just ran your code as it is and had no problem with it as long as I am not in debug mode

Sammy,
I tried it in the browser, but unfortunately, while I don't get the error, the validation doesn't work either.  If you uncheck your Disable Script Debugging option in the browser you will see that the error occurs even when not in debug mode.  It's just ignored if that option if disabled.

Well, we are planning to upgrade to ASP.NET 3.5, but not today :)  So, in the meantime, I'm SOL?
