    taskInstance or processInstance gets Lost during execution

    Anthony Yulo Newbie

      I have developed a simple approval process using JBPM.


      Basically I have a home page for the approver, which displays a list of documents that needs to be approved. 


      <h:dataTable value="#{taskInstanceList"} var="task" ... >)
      



      On each row, i also put in an s:link tag so I can direct the approver to another page where he can review and where the approve button would be.


      <s:link ... taskInstance=#{task}> 
      



      However, I when I go to the document page, I put in an outputText with a value of taskInstance.id for tracing purposes, and noticed that is not display anything or is null.


      <h:outputText value="#{taskIntance.id}"> 
      



      Also on the document page, I have the Approve button which calls a method ApproveMe which has an annotation BeginTask.


      ...
      ...
      @BeginTask
      public String ApproveMe() {
      
      //doSomethingToApprove
      
      }
      ...
      

       


      I get an Exception saying


      task/process id may not be null
      



      So I think, the taskInstance variable or pointer got lost along the way.


      Any Ideas?
