Multi-part content in nested forms (Wicket 6.0)
Hi all,
I have been experiencing some problems with nested forms lately. I have
an outer form which contains a FileUploadFile and an inner form with no
upload field. If I submit the inner form in *AJAX* mode, I get the
following error:
Last cause: 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.
even though the outer form has its setMultiPart(true).
Adding setMultiPart(true) to the inner form (even though it makes no
sense at all) breaks the JavaScript:
ERROR: Wicket.Ajax.Call.submitForm: Trying to submit form with id
'undefined' that is not in document.
even though its setOutputMarkupID(true) is set.
I have also tried the following
public boolean wantSubmitOnNestedFormSubmit() {
return false;
}
on the outer form, but I had no luck at all.
I would really appreciate if you could help me with this.
Best
Pouyan

Update:
the problem is solved if you add the outer form to the
AjaxFallbackButton of inner from, so instead of
new AjaxFallbackButton("innerSubmit",innerForm)
you should do
new AjaxFallbackButton("innerSubmit",outerForm)
Sorry for the fuss.

Update:
Considering following cases:
1) Outer form has its multipart set to true and inner form to false:
when inner form is submitted, a GET AJAX request is sent to server. The
outer list however is a multipart one and expects a post request (see
L#64 ServletFileUpload), thus the exception is thrown.
2) Both forms has their setMultipart to true:
when the inner form is submitted via AJAX, since it is a multipart form,
a new iframe (containing a submit button) is created and the JavaScript
function submit() is called on the inner form. On the other side, since
the inner form is just a div and no real form, the function fails.
up to now, I haven't come up with a solution, which adequately addresses
this problem. I also didn't want to make any changes to JS files.
Best,
Pouyan
