    task variable in java @endtask function

    turpin vincent Newbie



      Hi, i'm using Seam 2.1 and i'm in trouble with task variable gestion

      In the third taskInstance  of a processInstance i want to get a variable (witch is in Process scope) in a function but i dont find how...

      In this part:


      `                  <h:column>
                              <f:facet name="plop">
                                  <h:outputText value="Voiture"/> 
                              </f:facet>
                              <h:outputText value="#{task.variables['sinistre'].typeVoiture}"/>  <br />
                         </h:column>
                             
                         <h:column>
                              <f:facet name="header"> 
                                  <h:outputText value="type de Voiture"/> 
                              </f:facet>
                              <h:inputText id="typeVoiture" value="#{Saisie_1.sinistre.typeVoiture}"/>                                                                 
                         </h:column>

                          <h:column>
                              <s:button value="ajouter" taskInstance="#{task}" action="#{Saisie_1.Ajout_Mat}" />                                                               
                          </h:column>`

      I update task variable {task.variables['sinistre'].typeVoiture} with a value from the input text {Saisie_1.sinistre.typeVoiture}
      and it works but then i want to get this value in my function in order to persist this value.


      `       @StartTask 
         @EndTask(transition="toJoin2")
         public void Ajout_Mat()
              {    
                 System.out.println("ajout du type de voiture");
                 System.out.println("voiture avant set: "+ sinistre.getTypeVoiture());
                 sinistre.setTypeVoiture(sinistre.getTypeVoiture());
                 System.out.println("voiture apres set: "+sinistre.getTypeVoiture());
                 this.ajouterInfoMat();
                 System.out.println("Sinistre mat maj et transmis");
              }
         `

      but i dont find how

            sorry, I didn't check all that code, but this is what works for me in a component:



                @In(scope = ScopeType.BUSINESS_PROCESS, required = false)
                @Out(scope = ScopeType.BUSINESS_PROCESS, required = false)
                private String processActorId;



            I also wondered why Saisie_1 doesn't implement Serializable and why sinistre is static, looks a bit strange at me, but that's just my first impression...

              Thanks for your reply, in fact it's in static because if not, value are cleaned when i leave the first task.
              I will try with your code and tell you what append.

                you can also check the JBPM_VARIABLEINSTANCE table to see if the variable gets persisted

                  i'checked that

                  with:


                  @In(scope = ScopeType.BUSINESS_PROCESS, required = false)
                      @Out(scope = ScopeType.BUSINESS_PROCESS, required = false)
                      private String processActorId;

                  it work like with


                      @Out(scope = ScopeType.BUSINESS_PROCESS, required = false)
                      private static String processActorId;

                  but i still can't get the value

                         </f:facet>
                             <h:inputText id="typeVoiture" value="#{task.variables['sinistre'].typeVoiture}"/>
                         </h:column>

                  with:

                  System.out.println("voiture avant set: "+ sinistre.getTypeVoiture());

                  in order to persist it with :

                  entityManager.merge(sinistre);

                    you don't need to persist the task instances, Seam should do this job for you. I recommend you take a look at Dan Allen's Seam in Action chapter 14 is available online at http://www.manning.com/dallen/ and covers the jBPM stuff, (it's a great book BTW)

                      Thanks for this advice (even if i still read this chapter) i know that Seam should do that, but i need to persist some information from this task in a spécific table in order to deal with an other application. So i will read this doc with more attention and maybe buy this book.

                        BTW is that possible to pass an argument by this way:

                        <h:column>
                               <s:button value="ajouter" taskInstance="#{task}" action="#{Saisie_1.Ajout_Mat(task.variables['sinistre'].typeVoiture})" />
                        </h:column>
