CompanyDirectory FE listing submit problem

[nidus]

the file upload in the frontendform doesn't pass the file name (logo_location, picture_location), the $_POST for those inputs are empty.
template with latest jquerytools and {cgjs_require lib='ui, fileupload'} and {cgjs_render} in the page header or at the page end (no difference)
Anyone with the same problem or found a solution?
