["Alex Grant (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/WICKET-2621?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12791156#action_12791156 ] 

Alex Grant commented on WICKET-2621:
------------------------------------

I don't know for certain that this appeared in 1.4.4, as we have upgraded directly from 1.4.1. WICKET-2553 was preventing us from using 1.4.2 and 1.4.3.

> I have a ModalWindow that contains an IndicatingAjaxButton. When I click the button, I get a big Java error complaining that the form submit wasn't multipart.
> Digging into the javascript in wicket-ajax.js, I found this from line 1102 in the method handleMultipart
> {code}
> multipart=multipart||form.enctype=="multipart/form-data";
> if (multipart==false) {
>      // nothing to handle
>     return false;
>  }
> {code}
> When this executed, multipart was false, and enctype was "" and therefore the submit aborted. This may be the cause.
> Here's the Java stacktrace
> {noformat}
