Another SA2 BUG i think uploading files on a registration

I can not make the registration page have an upload field on the wizard it gives a javascript error if i select a field as file see attachment.

If i add manually the upload (with css form builder or dfp2 or any of the extensions that installs me the upload stuff) behavior it simply does not upload any file and also doesnt even register it, i have wasted 4 days trying to get this working i even deleted the insert from the SA2 wizard on the registration page and tested inserting a dataasisit insert behavior and no luck either, whats wrong with this extension i try everything before reporting the bug.

I also cleared and deleted dreamweaver cache, made a clean fresh install of the extensions, deleted the configuration folder also just in case no matter what i still keep getting that javascript error if i try to make the security assist use file field.

I really need to be able to let users upload a picture or pdf file when they register to the website, this SA2 still needs improvments im about to go back to SA1 wich i could do this without any problems

I need a ticket opened on this issue please

i will log a bug about the error message on adding a file up,load field.

to get the file upload to work, the forms encoding type must be set to multipart/form-data

<form class="Basic_Default" id="Registration_Basic_Default" name="Registration_Basic_Default" method="post"  action="<?php echo (htmlentities($_SERVER["PHP_SELF"]));?><?php echo(isset($_SERVER['QUERY_STRING'])?"?".str_replace("<","%3C",str_replace(">","%3E", str_replace('"',"%22", $_SERVER['QUERY_STRING']))):""); ?>">

to:

<form  action="<?php echo (htmlentities($_SERVER["PHP_SELF"]));?><?php echo(isset($_SERVER['QUERY_STRING'])?"?".str_replace("<","%3C",str_replace(">","%3E", str_replace('"',"%22", $_SERVER['QUERY_STRING']))):""); ?>" method="post" enctype="multipart/form-data" name="Registration_Basic_Default" class="Basic_Default" id="Registration_Basic_Default">
