I was testing these days the "add contact" process and I have something that seems to be a problem coming from joustsim. I know the you have the sources and you could debug that and that's why I'm addressing to you. Could you please check what happens if we try to create on the server a group, which is already there. The problem is that in some cases the createGroup operation fails and I found out that this happens in all cases where the group I'm trying to create has the same name as a group already existing on the server (in the GUI we could have different meta groups with the same name). In such a case no event comes for the ServerStoredGroupListener. Could you please have a look?
