Hi, Janne
In one of the PortletPages I have a scroll which on-selection-
changed should
update part of the page. This worked fine in web-app, but now in
portlet-app
fails for the following listeners-related-reason, it seems:

Any idea?
I guess the bypass-solution to this might be creating explicit-form-
submit
on scroll-selection-changed, so the same page is reloaded again, but
explicitly, without implicit-internall-listeners. Has it sense?
Hi.
dispatchEvent seems to happen when processing the multipart forms,
which might not work. Do you have a file upload input in your form,
if not, what happends if you set form.setMultiPart(false); ?
