Re: Form from post to multipart

[Martin Grigorov]

Hi,

Thanks for sharing your solution!
IMO this is a special case that is not that common to be in Wicket core.
It also assumes that Form#setOutputMarkupId(true) has been called.

What about marking the form as multipart from the beginning
(Form.setMultipart(true)) ? I think it should work even i there are no
FileUploadField fields in it.

Re: Form from post to multipart

[Илья Нарыжный]

Hello!

Issue has been solved by the following code. What do you think about
inclusion of it into official wicket code?

/**
 * Update Form EncType to "multipart/form-data" of there is something which
require multipart is in target ajax response
 */
public class FixFormEncTypeListener extends
AjaxRequestTarget.AbstractListener {

@Override
public void onAfterRespond(Map map, IJavaScriptResponse
response) {
Set formsToUpdate = new HashSet<>();
for (Map.Entry entry : map.entrySet()) {
Component component = entry.getValue();
Form form = component.findParent(Form.class);
if(form!=null && form.isMultiPart()) formsToUpdate.add(form.getRootForm());
}
for (Form form : formsToUpdate) {
response.addJavaScript("{var e =
document.getElementById('"+form.getMarkupId()+"'); e.encoding=
'multipart/form-data'; e.encType=e.encoding;}");
}
}
}

Thanks,

Ilya

Re: Form from post to multipart

[Илья Нарыжный]

It will not solve the problem... Component which want to be mutatable
doesn't want to know about parent forms. So forms in ajax mode should
somehow adjust encoding automatically, but resending of whole content of a
form is not good option, imho.

Thanks,

Maybe you can use nested forms?

Form from post to multipart

[Илья Нарыжный]

Hello!

Please help to figure out is there some good solution for the following
situation:

There is a page with Form with in it. Form contains lots of components
underneath. And some components can be changed by AJAX from "view"
representation to "edit". And sometimes "edit" is some file upload
component. And in this case to work proporly: form encoding should be
changed to multipart. But I don't want to make it by sending in ajax
response whole Form, because it's pretty big...  Is there a good way update
just a component and if parent form is not multipart - switch it to
multipart?

Thanks,

Ilya
