Complex Grids and Js_forms

[Wayne Germann]

Hello All,

I have a complex grid in a js_form in Studio 4321.   When ever i try to $remove the first line in the list or the last remaining line the list...it goes into an error:

"Exception caused while processing server response.
Line undefined: Invalid object number. Parameter error 17.
in file "undefined""

Does anyone have an idea what is causing this?

Thanks,
Brian
