PooledAction & groupAssignee

[tpeelen]

Hi all,

My purpose is to have a process that assigns a task to a predefined group of people. First one that takes the task prevents others from taking the same task. the group names participating are known and defined on forehand in the process definition…

I have the model:

<model name="wfictu:workflowmodel" xmlns="http://www.alfresco.org/model/dictionary/1.0">

  <imports>
     <import uri="http://www.alfresco.org/model/dictionary/1.0" prefix="d"/>
     <import uri="http://www.alfresco.org/model/bpm/1.0" prefix="bpm"/>
  </imports>

  <namespaces>
     <namespace uri="http://www.ictu.nl/model/workflow/1.0" prefix="wfictu"/>
  </namespaces>
      
  <types>

     <type name="wfictu:initTask">
        <parent>bpm:startTask</parent>

        <properties>

           <property name="wfictu:juridisch">
              <type>d:boolean</type>
              <default>true</default>
           </property>

           <property name="wfictu:controller">
              <type>d:boolean</type>
              <default>true</default>
           </property>

           <property name="wfictu:directie">
              <type>d:boolean</type>
              <default>true</default>
           </property>

     </properties>

     <mandatory-aspects>
           <aspect>bpm:groupAssignee</aspect>
      </mandatory-aspects>
 
    </type>

     <type name="wfictu:behandelTask">
        <parent>bpm:workflowTask</parent>

      <properties/>
        <mandatory-aspects>
           <aspect>bpm:groupAssignee</aspect>
        </mandatory-aspects>

     </type>


     <type name="wfictu:inkoopEindTask">
        <parent>bpm:workflowTask</parent>

      <properties/>

      <mandatory-aspects>
           <aspect>bpm:groupAssignee</aspect>
        </mandatory-aspects>

     </type>
      
  </types>
   
</model>

And the process definition:

<process-definition xmlns="urn:jbpm.org:jpdl-3.2" name="wfictu:bewakenvoortgang">

  
  <swimlane name="initiator"/>
  <start-state name="start">
    <task name="wfictu:initTask" swimlane="initiator" />
    <transition name="NaarJuridischeZaken" to="startJuridischeZaken"/>
  </start-state>
  
  <swimlane name="inkoop">
    <assignment class="org.alfresco.repo.workflow.jbmp.AlfrescoAssignment">
          <pooledactors>#{people.getGroup("GROUP_Inkoop")}</pooledactors>
    </assignment>
  </swimlane>

  <swimlane name="controller">
    <assignment class="org.alfresco.repo.workflow.jbmp.AlfrescoAssignment">

    <transition name="done" to="end"/>

A snippit of the web-client-config-custom.xml:

   <config evaluator="node-type" condition="wfictu:initTask" replace="true">
    <property-sheet>
     <separator name="sep1" display-label="tralala loempia" component-generator="HeaderSeparatorGenerator"/>
     <show-property name="wfictu:juridisch" />
     <show-property name="wfictu:controller" />
     <show-property name="wfictu:directie" />
     <!– show-association name="bpm:groupAssignee" / –>
   </property-sheet>
   </config>
   
    <config evaluator="node-type" condition="wfictu:behandelTask" replace="true">
    <property-sheet>
     <separator name="sep1" display-label="tralala loempia" component-generator="HeaderSeparatorGenerator"/>
     <show-property name="wfictu:juridisch" />
     <show-property name="wfictu:controller" />
     <show-property name="wfictu:directie" />
     <show-association name="bpm:groupAssignee" />
   </property-sheet>
   </config>
   
    <config evaluator="node-type" condition="wfictu:eindInkoop" replace="true">
    <property-sheet>
     <separator name="sep1" display-label="tralala loempia" component-generator="HeaderSeparatorGenerator"/>
     <show-property name="wfictu:juridisch" />
     <show-property name="wfictu:controller" />
     <show-property name="wfictu:directie" />
     <show-association name="bpm:groupAssignee" />
   </property-sheet>
   </config>
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

The result is dissapointing, I haven't got it running for days. It complains:

ERROR [ui.common.Utils] A system error happened during the operation: Mandatory task properties have not been provided: {http://www.alfresco.org/model/bpm/1.0}groupAssignee

If I include the <show-association name="bpm:groupAssignee" /> in the initTask definition I can select a group. I don't want to, because the groups are predefined…. I noticed a similar question in the forum, but the answer is not really working out (using #{people.getGroup("GROUP_…")}

Anyone a good idea or pointer???

Thanks in advance!

The groupAssignee assignment you do apparently isn't working.
If I do a groupAssignee in script (I run an advanced workflow triggered by a spacerule and executed by script) like this

workflow.parameters["bpm:groupAssignee"] = "Groep_Editors";

Where Groep_Editors is the group.name the rule runs fine and there are no complaints about mandatory groupAssignee's.

Just remove all…

 <mandatory-aspects> 
    <aspect>bpm:groupAssignee</aspect> 
 </mandatory-aspects>

from your model definition.  Having this specifies that the group assignee variable must be allocated (take a look at the bpm:groupAssignee aspect definition).  As you're hard-coding group assignments in your process definition, you don't need the variable.
