Thanks John.  Using Pharo Web Image 09.04.6, and the Seaside that came
packaged up with that ( not sure how to check the version ).

That's a good tip thanks.

The control is a meant to be little more sophisticated and can actually add
a new phone number between two phone numbers, it adds a new phone number
under whichever row you click "Add" on. I don't have it coded in, but if
there are no phone numbers yet, then the report would be simply be an "Add
Phone Number" link.

I'm glad to hear that's what it should do, now it's just a matter of
figuring out what strange thing I did to make it NOT do that.

I cleaned up those class methods and there was a halt in there too that
shouldn't have been. Attaching the .mcz seemed to be giving me problems this
morning so I just put it here for download:

It's just a test case with a method that creates a sample customer...doesn't
persist anything...it just demos the problem I'm having.
