I created two portlets to manage communication events with many participants.
- Edit portlet, list all parties associated to the current partyId by PartyRelationship with a roleTypeId passed to PortletAttribut
- List portlet, list all communications on the current partyId with all communicationRoles associated (expect partyIdTo and partyIdFrom)
I created a temp addon, available here http://caiman.nereide.fr/portlet-commevent-and-roles/
This is a first release. All suggestion are welcome
