Description

We are experiencing problems with Cocoon Forms under following circumstances:
- Using an AJAX-form
- with file-upload (using the IFRAME Dojo transport accordingly)
- using MSIE 6 or 7
- pressing the cancel button

In this case, an empty response is send. Because of browser limitations, an empty response is emulated using the bu:continue browser-update construct. Microsoft Internet Explorer expects always HTML response when dealing with the IFrame transport, so it cannot handle the XML-response (bu:continute) generated by Cocoon.
