[jira] Created: (COCOON-2027) [PATCH] Handling of empty responses in AJAX Forms with IFrame transport

[PATCH] Handling of empty responses in AJAX Forms with IFrame transport
-----------------------------------------------------------------------

                 Key: COCOON-2027
                 URL: https://issues.apache.org/jira/browse/COCOON-2027
             Project: Cocoon
          Issue Type: Bug
          Components: Blocks: Forms
    Affects Versions: 2.1.11-dev (Current SVN), 2.2-dev (Current SVN)
            Reporter: Jan Oberst


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.

Jan Oberst updated COCOON-2027:
-------------------------------

    Attachment: cocoon-iframe-continue.patch

This patch changes Form.js to check for the dojo.transport before sending a bu:continue. If the request is using the iframe transport, the bu:continue message is wrapped into an HTML file, making it possible to handle the response with MSIE.
