[jQuery] jquery.form.js -> multiple simultaneous ajax form submissions

[Jim]

I have a page with the following properties:
Several non-form input elements (a text field, a few buttons).
    There is an "add file" and a "remove file" button. Whenever the
"add file" is clicked, new_file_count is incremented and a form is
created (ID: "nc-" + new_file_count, NAME: "ncform", enctype:
"multipart/form-data"). Whenever "remove file" is clicked, the last
form is removed, and new_file_count is decrimented. Each form has a
hidden submit element named "NEW_SUBMIT".
    There is also a text field button, when it is clicked, a hidden
field in each form is updated, along with the text in a span element
within each form. This works properly.
    Finally, there is the non-form "Check in documents" button. When
this is clicked, the function LAC_NEW_CHECKIN_CLICK is called (see end
of mail). This should iterate through each form, and submit it, and
the alerts I put in the validation function would suggest it is doing
that. However, when the actual LAC_submit_checkin function is
executed, the checkin is not being executed as AJAX (I'm redirected to
the json output of the first form).

Any idea what would could cause causing this? The AJAX setup/trigger
is in LAC_submit_checkin

Thanks,

  myform.ajaxForm(options);
