ewmode...
This is not yet possible. maybe we see something like that in one of the
next versions of the portlet spec. but that will take some time.

wishlist / javascript support
Posted by Jason Novotny <no...@aei.mpg.de>.
Echoing a request earlier that Stephan Hesmer approved, I too would
like to see better support for integrating JavaScript in with portlets--
it looks like it would require buffering though which is fine I think.
The current approach of duplicating JS in each portlet is not very good.
