Cedric Thiebault commented on WICKET-3236:
------------------------------------------
Point 1) was not a bug, I just needed to set multipart on parent form:

But 2) still open...

> I want to upload file with an Ajax form that is in a modal window. The modal
> and its form are part of the main form.
> 1) 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.

> - mvn jetty:run
> - click on "Add new file (panel modal)" and upload a file
> - then, once the modal is closed, click on "Submit input text"
> --> exception
> 2) I've also tried to use a modal with a WebPage instead of a Panel: it works
> well except that the DataTable does not reflect the new uploaded files...
> even if everything is fine in background with models.
> Any ideas of what I did wrong here? Is it because of AjaxRequestTarget
> between pages and panels?
> Thanks for your help.
