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?

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>
