Hi,
I want to upload files with an Ajax form that is in a modal window
(using a Panel, not a WebPage). The modal and its form are part of the
main form:
main-page.html
<form wicket:id="form">
<div wicket:id="modal" />
<input type="submit" wicket:id="submit" />
</form>
upload-window.html
<form wicket:id="form">
<input type="file" wicket:id="file" />
<input type="submit" wicket:id="submit" />
</form>
I'm able to upload a file but once the modal is closed, when I submit
the main form (not the one for uploading), I get an exception:
java.lang.IllegalStateException: ServletRequest does not contain
multipart content. One possible solution is to explicitly call
Form.setMultipart(true), Wicket tries its best to auto-detect
multipart forms but there are certain situation where it cannot.

I've created a JIRA issue with code example
(https://issues.apache.org/jira/browse/WICKET-3236) but maybe I
misunderstood something here...
Any help would be appreciated ;-)
Thanks
Cedric
