Multiple assignee controls in Alfresco Workflow form

Question

I'm required to build a workflow that allows the admin to select two assignees from two different groups in the first task of the workflow. Can I use two assignee controls in one form ? How?

Answer 1

You need to:

• In the task content model, define the 2 assignees as 2 seperate associations of your task type.

      <type name="my:starttask">
      <parent>bpm:startTask</parent>
        <associations>
          <association name="my:firstassignee">
              <title>firstassignee</title>
              <source>
                  <mandatory>false</mandatory>
                  <many>false</many>
              </source>
              <target>
                  <class>cm:person</class>
                  <mandatory>false</mandatory>
                  <many>false</many>
              </target>
          </association>
          <association name="my:secondassignee">
              <title>secondassignee</title>
              <source>
                  <mandatory>false</mandatory>
                  <many>false</many>
              </source>
              <target>
                  <class>cm:person</class>
                  <mandatory>false</mandatory>
                  <many>false</many>
              </target>
          </association>
      </associations>
     </type>
  

• In your share config custom, define the 2 associations as authority controls:

        <config condition="activiti$myworkflow" evaluator="string-compare">
          <forms>
           <form>
          <field-visibility>
              <show id="my:firstassignee" />
              <show id="my:secondassignee" />
           </field-visibility>
          <appearance>
              <field set="actors" id="my:firstassignee" >
                  <control template="/org/alfresco/components/form/controls/authority.ftl">
  
                  </control>
              </field>
  
              <field set="actors" id="my:secondassignee">
                  <control template="/org/alfresco/components/form/controls/authority.ftl">
  
                  </control>
              </field>
  

• In your bpm20 file, define two ActivitiScriptNode vars in your process and an ExecutionListener to the usertask/starttask having the two cm:person associations. That execution listener should be taking the entered values and placing them into the process scoped variables like this:

    <extensionElements>
      <activiti:taskListener class="org.alfresco.repo.workflow.activiti.tasklistener.ScriptTaskListener" event="complete">
        <activiti:field name="script">
          <activiti:string>
             execution.setVariable('firstActivitiScriptNodeVar', task.getVariable('my_firstassignee'));
             execution.setVariable('secondActivitiScriptNodeVar', task.getVariable('my_secondassignee'));
          </activiti:string>
        </activiti:field>
      </activiti:taskListener>
    </extensionElements>
  

• Then add this code to the UserTasks you which to assign to the entered users like this:

  <humanPerformer>
              <resourceAssignmentExpression>
                  <formalExpression>${firstActivitiScriptNodeVar.properties.userName}</formalExpression>
              </resourceAssignmentExpression>
  </humanPerformer>
