How to assign user to task

As we transition to the new Hyland Community, some post links may be temporarily disrupted as we finalize redirects. We apologize for the inconvenience and are working to resolve this as quickly as possible. Details.

Please take a look at my process definition and task model below:
[img]http://demo.dtn.com.vn/download/processimage.jpg[/img]

There're 4 steps in the process and I want users to be able to assign different user in each step. I deployed the definition successfully but only in the first step, I can select user to assign to, the subsequent steps, there's no select box to choose user.

Process definition:

<?xml version="1.0" encoding="UTF-8"?>
<process-definition
  xmlns="urn:jbpm.org:jpdl-3.1"  name="wf:testProcess">
  
   <swimlane name="initiator"></swimlane>
   <swimlane name="secretary">
      <assignment actor-id="#{bpm_assignee.properties['cm:userName']}" />
   </swimlane>
   <swimlane name="manager">
      <assignment actor-id="#{bpm_assignee.properties['cm:userName']}" />   
   </swimlane>
   <swimlane name="chief">
      <assignment actor-id="#{bpm_assignee.properties['cm:userName']}" />   
   </swimlane>
   <swimlane name="officer">
      <assignment actor-id="#{bpm_assignee.properties['cm:userName']}" />  
   </swimlane>
   
   <start-state name="start">
      <task name="wf:enterDocTask" swimlane="initiator"></task>
      <transition name="" to="preProcessDoc"></transition>

Hi,

You need to configure the UI dialog for each of your new tasks to allow the user to select the next workflow participant.

e.g.

in web-client-config-properties.xml, add the following for your "Pre Process" task…

<config evaluator="node-type" condition="wfreProcessDocTask" replace="true">
   <property-sheet>
      <separator name="sep1" display-label-id="general" component-generator="HeaderSeparatorGenerator" />
      <show-property name="bpm:workflowDescription" component-generator="TextAreaGenerator" />
      <separator name="sep2" display-label-id="users_and_roles" component-generator="HeaderSeparatorGenerator" />
      <show-association name="bpm:assignee" />
   </property-sheet>
</config>

and repeat for your other tasks.  Each task dialog can display/edit its own set of properties.

Just one comment on your definition.  I see you're re-using bpm_assignee in each of the tasks.  That's ok with your serial process, however, the bpm_assignee will be overwritten in each step.  If you want to maintain all the assignees during the workflow, and refer to them later on, you can use a different association name for each.
