It sounds excellent to me, thanks sohil. Now I like to get an answer from Julien or Thomas as they both say I can change layout for a page and region for a portlet. It needs to be in the PortalNodeEventListener and for the page being displaid. The classes I get there are PortalNode, PortalRuntimeContext and NavigationalStateContext. PortlaNode has a map of properties and I suppose I could change properties in there, what properties and will it be sufficient? Changing layout needs a full redraw, changing region may not need a full redraw (as opposed as partial refresh), that's why I have doubts about their answer.
