File upload with inner form and modal window
--------------------------------------------
Key: WICKET-3236
URL: https://issues.apache.org/jira/browse/WICKET-3236
Project: Wicket
Issue Type: Bug
Components: wicket
Affects Versions: 1.4.14
Reporter: Cedric Thiebault
Attachments: wicket-modal-upload.zip
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.

Use the quick start I've uploaded to reproduce this:
- 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.
