create groups or membershiptype within a portlet

[jeremie garcia <jeremie.garcia@xxxxxxxxxxx>]

hello

I am trying to manipulate the groups within a portlet that I've developped
with the following code, if the group geo doesn't exist it seems to be 
created, but then it doesn't appear in the user/organisation portlet.

           g = groupHandler.findGroupById("/geo");
           if(g == null){
               g = groupHandler.createGroupInstance();
               g.setGroupName("geo");
               g.setLabel("geo");
               groupHandler.addChild(null, g, true);               
           }

I've seen something about groupEventListener, should I use it?
and how should I use it?

the problem is the same if I deal with MemberShipType..

thanks for your help.
