Greetings,

On a portal page, I'd like to have a portlet and a kind of placeholder, such that, given the interactions in the portlet, to be able to render another portlet in the placeholder. Of course, the second portlet choice should be based on the actions in the first portlet. I don't find any idea to do that si I'd be very gratefull if someone knows how to do it.

Many thanks in advance,

Nicolas
