I have applied your patch (WICKET-2663-problem2.patch) to wicket-1.4.5 (I also tried the trunk but couldn't make it compile).
Firefox 3.5.6 and IE8 both work.
Chrome 3.0 is still broken, with the error mentioned at the bottom of the Description above:

ERROR: Wicket.Ajax.Call.failure: Error while parsing response: Could not find root <ajax-response> element
INFO: Invoking post-call handler(s)...
INFO: Invoking failure handler(s)...
INFO: Response parsed. Now invoking steps...
ERROR: Wicket.Ajax.Call.processEvaluation: Exception evaluating javascript: SyntaxError: Unexpected end of input
INFO: Response processed successfully.
INFO: Invoking post-call handler(s)...
INFO: refocus last focused component not needed/allowed

This error is particularly bizarre as if I put a web proxy in (to capture the invalid response) the problem goes away.

>             Project: Wicket
>          Issue Type: Bug
>    Affects Versions: 1.4.5
>            Reporter: Alex Grant

>
> I have a wicket page, with a URL several levels deep that contains
> * An initially hidden file upload field (so that multipart is used)
> * A link to open an ajax modal popup
> * An initially empty table
> I am also using UploadWebRequest to allow the upload progress bar to work.
> When I open the popup, type some data and close the popup, it tries to re-render the table with an extra row, which includes an ajax link to re-show the popup to allow editing. This fails.
> At least part of the problem is that the ajax response contains an invalid link to wicket-ajax.js. It should start with "../../", but that is lost when using UploadWebRequest, as newMultipartWebRequest creates a child request that has no interface parameter and therefore a urlDepth of -1.
> Changing the application to use the standard ServletWebRequest solves the problem for Firefox and IE8, but Chrome still fails. I have been unable to determine the cause of this. The Wicket Ajax Debug Log shows this:
> ERROR: Wicket.Ajax.Call.failure: Error while parsing response: Could not find root <ajax-response> element
> INFO: Invoking post-call handler(s)...
> INFO: Invoking failure handler(s)...
> INFO: Response parsed. Now invoking steps...
> ERROR: Wicket.Ajax.Call.processEvaluation: Exception evaluating javascript: SyntaxError: Unexpected end of input
> INFO: Response processed successfully.
> INFO: Invoking post-call handler(s)...
> INFO: refocus last focused component not needed/allowed
