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:
<error>

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?
Cheers
