Submitting form with attachments.

Question

Hi,
I have a simple need. I am stucked in it. What i need to do is:
Step 1: User1 starts opens a pdf form inside LC Workspace, fill it, attach files (Reader Extended) and then submit it.
Step 2: User2 receives the filled form with attcachments. Can view attachments and save them in repository.
I am stucked at step 1. User is able to fill the form, add attachments but can't submit it. If I am not enabling the Reader Extensions for attachments (Disabling functionality to attach files) then it works fine. But when using with attachments option, it fails. It gives no error, no message and does not passed to the 2nd user.
Is there any special requirement in developing such process/form ??
Please help me out on it.

I've studied the HTML generated by UIX and it has following bugs and misfeatures:
1. Misfeature: Submitting with Enter works ONLY if there is exactly one text field in the form (no submit button is actually needed), as Brian Stoler wrote. I don't understand reason for this.
2. Bug: UIX generates javascript function "_submitOnEnter" which is called as event handler for "onKeyPress" event. But this function is erroneously generated multiple times, once for each form in the page. Browsers (Mozilla and IE) use the latest implementation. This function is different for forms with one text field and for forms with more text field, but only the first one can do the job. As a consequence of this, Enter can submit the form only if the last form on a page has single text field (which is for example not the case of search form with single field above another form...)
Tested with UIX 2.1.7 in JDeveloper 9.0.3.3, using UIX as JSP tag library.
Workaround:
1. Use Opera browser: it submits form with enter key even if there is no submit button (this does not work for the first text field in the form, because it has "onkeypress" event handler).
2. Implement this feature by hand yourself, if you really need it (see below).
3. Use accessKey: allows to submit form with Alt+<key> combination (followed by Enter with IE).
Implementing Enter key submits with Javascript:
1. Put the following function to the header (or to javascript library):
function enter(e, frm) {
var kc;
if(window.event) kc=window.event.keyCode;
else if(e) kc=e.which;
else return true;
if(kc==13) {
submitForm(frm,1);
return false;
Function copied from UIX (C).
2. Add this event handler to each input element:
onKeyPress="return enter(event, 'formName');"
It is obvious that this is error prone, but it works with all browsers...
Will this be fixed in future versions?
Why only form with one text field can be submitted?
