Subject [jira] Updated: (COCOON-2027) [PATCH] Handling of empty responses in AJAX Forms with IFrame transport
Date Thu, 22 Mar 2007 18:58:32 GMT

     [ https://issues.apache.org/jira/browse/COCOON-2027?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

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.

> 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.
