Hi Guys ,

Does anyone of you know how to send an AgentAction which has a pointer
on an concept instance

thanks for your help

khalil

this is what i did:

public Connection conn = new Connection; //Connection is a Concept

public Reserv_Connection resCon = new Reserv_Connection;//Res_conn is an
Agentaction

conn.setdata("...");

  resCon.setConnection(conn);//Reserv_Connection has two methods set and
getConnection which get and set and instance of connection
//////////jade.content.onto.basic.Action
        Action action = new Action();
        action.setActor(receiver);
        action.setAction(resCon);

        //need a content Element for the ACL message
        ContentElementList content = new ContentElementList();
        content.add(action);
  try{

          //msg.setContent();
          getContentManager().fillContent(msg, content);
          send(msg);
          }catch(Exception e){e.printStackTrace();}

in the receiver i got the Resev_Connection but when i try to get also
the instance of connection which is pointed by Reserv_COnnection, i got
NullpointerException
