Ajax buttons inside ModalWindows don't submit properly
------------------------------------------------------
Key: WICKET-2621
URL: https://issues.apache.org/jira/browse/WICKET-2621
Project: Wicket
Issue Type: Bug
Affects Versions: 1.4.4
Reporter: Alex Grant
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
