These examples might help...
If you’re not using AJAX then it probably makes more sense to put the Form
around the Loop:
T5.4:

If you’re using AJAX, then a Form per row works well:

Hello,
I have a loop that creates a few forms and I have implemented the onValidate
method to validate the input. If an error occours in the textarea of the
first form, the textareas of all other forms are marked as erroneous too,
although the forms and textareas have different IDs. Whats wrong?
Thanks in advance.
M.B.
