I would like to refresh only one portlet when a processAction concerns only a portlet (i mean no event is send during the processAction call)

I have tried to set the partial refresh property to true but it is always set on false.

I use jboss portal 2.7.2

How to set this property on true without using the administrator interface?

Is it possible to set this property throug a generic way (to use my portlet with another portal) ?
