    Movo to node

    gar jar Newbie

      I've defined a process like this.


      <?xml version="1.0" encoding="UTF-8"?>
      <process-definition xmlns="urn:jbpm.org:jpdl-3.2" name="reserva">
       <swimlane name="reception">
       <assignment actor-id="pepeito"></assignment>
       </swimlane>
       <start-state name="Offer petition">
       <task name="Offer petition" swimlane="reception">
       <controller></controller>
       </task>
       <transition to="searchClient" name="search"></transition>
       </start-state>
       <task-node name="Create client">
       <task name="Create client" swimlane="reception">
       <controller></controller>
       </task>
       <event type="node-enter">
       <action class="com.aixtelecom.actions.CreateClientAction"></action>
       </event>
       <transition to="Create offer" name="crear oferta"></transition>
       </task-node>
       <task-node name="Create offer">
       <task name="Create offer" swimlane="reception">
       <controller></controller>
       </task>
       <event type="node-enter">
       <action class="com.aixtelecom.actions.CreateOfferAction"></action>
       </event>
       <transition to="Createbooking" name="yes"></transition>
       <transition to="finish" name="no"></transition>
       </task-node>
       <task-node name="Createbooking">
       <task name="Createbooking" swimlane="reception">
       <controller></controller>
       </task>
       <transition to="finish" name="Fi"></transition>
       </task-node>
       <node name="searchClient">
       <event type="node-enter">
       <action class="com.aixtelecom.actions.SearchClientAction"></action>
       </event>
       <transition to="Create offer" name="tr_create_offer"></transition>
       <transition to="Create client" name="tr_create_client"></transition>
       </node>
       <end-state name="finish"></end-state>
      </process-definition>
      


      At seachClient node i've created action handler on node-enter.
      This action is:
      public class SearchClientAction implements ActionHandler{
      
       /** The log. */
       private Logger log = Logger.getLogger(SearchClientAction.class);
      
       private static final long serialVersionUID = 3364679100134686576L;
      
       public void execute(ExecutionContext context) throws Exception {
      
       [connection with external mysql data base]
      
       if (result of query){
       //go to create offer
       node.leave(context, "tr_create_offer");
       }
       else{
       //go to create client
       node.leave(context, "tr_create_client");
       }
       }
      }
      


      I want depending on result of query, automatically process go to create client or create offer.
      On create client node and create offer node i've configured actions with
      System.out.println("Running on CreateClientAction...");
      or
      System.out.println("### Running on CreateOfferAction");

      When i start the process and enter on searchClient node, always the process finish into create offer node.

      17:06:49,000 INFO [STDOUT] Running on CreateClientAction...
      17:06:49,000 WARN [ProxyWarnLog] Narrowing proxy to class org.jbpm.graph.node.TaskNode - thi
      s operation breaks ==
      17:06:49,000 INFO [STDOUT] ### Running on CreateOfferAction
      


      Any idea?

          what happens if the value of "result of query" is explicitly true? if that fails, please make a unittest that I can cut and paste (in one file) to try it out....

            In this case

             if (true){
             //go to create offer
             node.leave(context, "tr_create_offer");
             }
             else{
             //go to create client
             node.leave(context, "tr_create_client");
             }
            


            the result is

            09:31:22,750 INFO [STDOUT] ### Running on CreateOfferAction
            09:31:22,781 INFO [STDOUT] ### Running on CreateOfferAction
            


            Seems that node changes how code is defined, but at last time always go to CreateOffer node.

              so, maybe the response of your query is not (always) correct?

              • 4. Re: Movo to node

                Yes. Query response it's correct.
                In exemple, If I execute this ActionHandler

                public class SearchClientAction implements ActionHandler{
                
                 /** The log. */
                 private Logger log = Logger.getLogger(SearchClientAction.class);
                
                 private static final long serialVersionUID = 3364679100134686576L;
                
                 public void execute(ExecutionContext context) throws Exception {
                
                 [connection with external mysql data base]
                
                 if (1==1){
                 //go to create offer
                 node.leave(context, "tr_create_offer");
                 }
                 else{
                 //go to create client
                 node.leave(context, "tr_create_client");
                 }
                 }
                }
                


                Result will be
                INFO [STDOUT] ### Running on CreateOfferAction
                INFO [STDOUT] ### Running on CreateOfferAction

                If I execute this code

                public class SearchClientAction implements ActionHandler{
                
                 /** The log. */
                 private Logger log = Logger.getLogger(SearchClientAction.class);
                
                 private static final long serialVersionUID = 3364679100134686576L;
                
                 public void execute(ExecutionContext context) throws Exception {
                
                 [connection with external mysql data base]
                
                 if (1==2){
                 //go to create offer
                 node.leave(context, "tr_create_offer");
                 }
                 else{
                 //go to create client
                 node.leave(context, "tr_create_client");
                 }
                 }
                }
                


                Result will be
                INFO [STDOUT] Running on CreateClientAction...
                INFO [STDOUT] ### Running on CreateOfferAction

                  sorry, then you are on your own... if it works with static true/false, but not with your query, we can't help you

                    I think that i haven't explained very well.

                    In all actions, (static true/false, query result, equals between int, string...) when code execute

                    node.leave(context, "name of transaction");
                    

                    always, the process enter into 2 nodes. Into node that execute code, and other node.
                    In exemple.
                    If I execute node.leave(context, "tr_create_client"); without if, always proces go to node :
                    first: create client node
                    second: create offer node.

                      sorry, but to me this does not make it much more clear... make a real unit test with embedded processdefinition (as string) and inner class for action.... then we can have a look

                        Sorry kukeltje.
                        Can you say some link that explain how to make unit test? I've never made it.
                        Thanks!!

                          http://www.junit.org/

                          and look at (almost) *all* the testcases in the jbpm source for real jbpm related examples
