Error in parentFormOnSubmit()

i’m using Form integrate method to send data to server.
after load from xml and edit any cell and submit. it’s work correctly.

Since when i added or deleted row by

mygrid.addrow(…)

after that when call function mygrid.parentFormOnSubmit();
and form.submit();
it shows that error in javascript and stop. i found that it’s stop on parentFormOnSubmit
and show “Error on page.”
