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<String, Component> map, IJavaScriptResponse
response) {
Set<Form<?>> formsToUpdate = new HashSet<>();
for (Map.Entry<String, Component> 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
