repeatChildren and newNodeset have different sizes?

>  I'm designing a fairly simple form and I'm getting a "repeatChildren and

>  I remember this one from a while ago (in nested repeats) but thought it had

>  In this case, I have three repeats in the same form but not nested. The

>  The View tab is the form with problem and the XML tab shows the document
> instance.
>  The repeats are over the top level <nickname>, <description> and
> <namespace> elements
>  - The default instance has no <namespace> element and works fine
>  - To recreate the problem, in Select Specification drop down, pick "DDI
> Codebook". This contains a <namespace> element and displays properly.
