how to assign two different assignees to different tasks?

targa2000 — Thu, 04 Mar 2010 09:34:55 GMT

defining a custom advanced workflow, looking at the Workflow Lifecycle Sample:http://wiki.alfresco.com/wiki/WorkflowSample_LifecycleThis code here seems to assign the task to an assignee: <swimlane name="reviewer"> <assignment class="org.alfresco.repo.workflow.jbpm.AlfrescoAssignment

You would need a second bpm:assignee or something along the same lines. It'd probably be easiest to create your own aspects for each assignee, something like:


     <aspect name="my:t1Assignee">
            <associations>
                <association name="my:t1Assignee">
                    <source>
                        <mandatory>false</mandatory>
                        <many>false</many>
                    </source>
                    <target>
                        <class>cm:person</class>
                        <mandatory>false</mandatory>
                        <many>false</many>
                    </target>
                </association>
            </associations>
        </aspect>
     <aspect name="my:t2Assignee">
            <associations>
                <association name="my:t2Assignee">
                    <source>
                        <mandatory>false</mandatory>
                        <many>false</many>
                    </source>
                    <target>
                        <class>cm:person</class>
                        <mandatory>false</mandatory>
                        <many>false</many>
                    </target>
                </association>
            </associations>
        </aspect>
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

You'd set each of your assignees at the start of the workflow and assign each assignee their respective task.

the fork is interesting. It seems most applicable for tasks that need to be done in parallel and with an unknown number of nodes. Is this right?

In my situation. I have two tasks that I know need to be completed each by a different person and tasks need to be completed in sequence, one after the other.

I have created a process definition file where I have defined two tasks and an assignee. The assignee gets assigned the first task. The task completes and that is it. I can't tell when the second task takes place. And there is not another assignee.

Here's the process definition file I have created so far:

<?xml version="1.0" encoding="UTF-8"?>

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

    <swimlane name="initiator" />

   <start-state name="start-state1">
       <task name="wf:submitAdhocTask" swimlane="initiator"/>
      <transition to="task-node1"></transition>
   </start-state>

   <swimlane name="assignee">
      <assignment class="org.alfresco.repo.workflow.jbpm.AlfrescoAssignment">
         <actor>#{bpm_assignee}</actor>
      </assignment>
   </swimlane>

   <task-node name="task-node1">
      <task name="wf:adhocTask" swimlane="assignee">
         <event type="task-create">
            <script>
               if (bpm_workflowDueDate != void) taskInstance.dueDate = bpm_workflowDueDate;
               if (bpm_workflowPriority != void) taskInstance.priority = bpm_workflowPriority;
            </script>
         </event>
      </task>
      <transition to="task-node2"/>
   </task-node>

   <task-node name="task-node2">
      <task name="wf:adhocTask" swimlane="assignee">
         <event type="task-create">
            <script>
               if (bpm_workflowDueDate != void) taskInstance.dueDate = bpm_workflowDueDate;
               if (bpm_workflowPriority != void) taskInstance.priority = bpm_workflowPriority;
            </script>
         </event>
      </task>
      <transition to="end-state1"/>
   </task-node>

   <end-state name="end-state1"></end-state>

</process-definition>

You'd set each of your assignees at the start of the workflow and assign each assignee their respective task.

It's a good idea. But how would you implement it?

I tried one way without much luck:

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

    <swimlane name="initiator" />

   <start-state name="start-state1">
       <task name="my:submitNewRequest" swimlane="initiator"/>
      <transition to="task-node1"></transition>
   </start-state>

   <swimlane name="assigneeone">
      <assignment class="org.alfresco.repo.workflow.jbpm.AlfrescoAssignment">
         <actor>#{my:t1Assignee}</actor>
      </assignment>
   </swimlane>

   <task-node name="task-node1">
      <task name="wf:adhocTask" swimlane="assigneeone">
         <event type="task-create">
            <script>
               if (bpm_workflowDueDate != void) taskInstance.dueDate = bpm_workflowDueDate;
               if (bpm_workflowPriority != void) taskInstance.priority = bpm_workflowPriority;
            </script>
         </event>
      </task>
      <transition to="task-node2"/>
   </task-node>

   <swimlane name="assigneetwo">
      <assignment class="org.alfresco.repo.workflow.jbpm.AlfrescoAssignment">
         <actor>#{my:t2Assignee}</actor>
      </assignment>
   </swimlane>

   <task-node name="task-node2">
      <task name="wf:adhocTask" swimlane="assigneetwo">
         <event type="task-create">
            <script>
               if (bpm_workflowDueDate != void) taskInstance.dueDate = bpm_workflowDueDate;
               if (bpm_workflowPriority != void) taskInstance.priority = bpm_workflowPriority;
            </script>
         </event>
      </task>
      <transition to="end-state1"/>
   </task-node>

   <end-state name="end-state1"></end-state>

deploying the above processdefinition and task model, the workflow options that are requested are only owner:_____ I don't know where that is coming from. none of the other options are requested on the startup page, then when it is finished, receive a number of exceptions, Script Exception t1Assignee is not defined.

You'll have to update the start task properties in the web-client-config-custom.xml to allow for those aspects to be set.


   <config evaluator="node-type" condition="my:submitNewRequest" replace="true">
      <property-sheet>
         <separator name="sep1" display-label-id="general" component-generator="HeaderSeparatorGenerator" />
         <show-property name="bpm:workflowDescription" component-generator="TextAreaGenerator" />
         <show-property name="bpm:workflowPriority" display-label-id="wf_review_priority" />
         <show-property name="my:notifyMe" />
         <show-property name="bpm:workflowDueDate" display-label-id="wf_review_due_date" />
         <separator name="sep2" display-label-id="users_and_roles" component-generator="HeaderSeparatorGenerator" />
         <show-association name="my:t1Assignee" display-label-id="wf_reviewer" />
         <show-association name="my:t2Assignee" display-label-id="wf_reviewer" />
      </property-sheet>
   </config>
‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Something like that.

Something like that.

Yes, that allows the various properties to be set including the two reviewers, but I'm still getting the same exception and error upon selecting finish to start the workflow:

Re: how to assign two different assignees to different tasks?

zladuric — Fri, 05 Mar 2010 16:19:05 GMT

I don't know if this can help you, but I guess it can't hurt.

My swimlanes (when I need to send the document all over the place) look like this (few different examples):


<swimlane name="firstReviewer">
      <assignment class="org.alfresco.repo.workflow.jbpm.AlfrescoAssignment">
         <actor>#{bpm_package.children[0].assocs["mycm:myReferrenceToSite"][0].assocs["mycm:theCustomAspectYouWereToldToUse"][0].properties.userName}
                        </actor>
                </assignment>
</swimlane>‍‍‍‍‍‍‍

<actor>#{companyhome.childByNamePath("MyCustomPlace").properties("somePropHoldingTheUsername")}</actor>‍

If it doesn't help you, maybe it will help me (by somebody pointing me to the error).

<swimlane name="assigneeone">
      <assignment class="org.alfresco.repo.workflow.jbpm.AlfrescoAssignment">

Hi Targa,

I'm just learning this stuff too, but using a colon in those doesn't seem correct. Just like you wouldn't put #{bpm:assignee} in there you would put #{bpm_assignee}, so I believe you should put #{my_t1Assignee} and #{my_t2Assignee} in there:


   <swimlane name="assigneeone">
      <assignment class="org.alfresco.repo.workflow.jbpm.AlfrescoAssignment">
         <actor>#{my_t1Assignee}</actor>
      </assignment>
   </swimlane>

   <swimlane name="assigneetwo">
      <assignment class="org.alfresco.repo.workflow.jbpm.AlfrescoAssignment">
         <actor>#{my_t2Assignee}</actor>
      </assignment>
   </swimlane>

Hi All,

In first ,thanks for targa2000 sample. Based on the example you provided,I have imitated an advanced workflow which runs through smoothly. Yet there's a problem there: under the " General " section,user can fill out relevant information like Description in frame box at the first step, but when it comes to the second step, there's no any frame box is displayed for the user to fill out nor any information is shown up under this section.The same problem repeats at the following steps. Pls help to resolve this problem.Below are the codes：

Re: how to assign two different assignees to different tasks?

roseta — Mon, 16 Aug 2010 20:16:44 GMT

Dear targa2000,

I think I have the solution you were asking for. Al least it works for me:

In the processdefinition you should define both swimlanes, reviewer and reviewer2:


…
 <swimlane name="initiator"/>
   
   <swimlane name="reviewer">
        <assignment class="org.alfresco.repo.workflow.jbpm.AlfrescoAssignment">
            <actor>#{bpm_assignee}</actor>      
        </assignment>    
    </swimlane>
   
   <swimlane name="reviewer2">
        <assignment class="org.alfresco.repo.workflow.jbpm.AlfrescoAssignment">
            <actor>#{bpm_assignee}</actor>      
        </assignment>    
    </swimlane>
…
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Then, in the your model, you should add the standar aspect in the two task, same as if you had only one swimlane, but do it in each task:


…
<type name="new:asignTask">
        <parent>bpm:workflowTask</parent>

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

     </type>

….

<type name="new:asignTask2">
        <parent>bpm:workflowTask</parent>

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

     </type>

…
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

and you should also add the asociation in you web-client-config-custom for both tasks:


…
<config evaluator="node-type" condition="new:asignTask" replace="true">
   <property-sheet>
      <separator name="sep1" display-label-id="general" component-generator="HeaderSeparatorGenerator" />
      <show-property name="bpm:workflowDescription" component-generator="TextAreaGenerator" display-label-id="newDescription"/>
      <show-property name="bpm:workflowPriority" display-label-id="newPriority"  />
      <separator name="sep2" display-label-id="users_and_roles" component-generator="HeaderSeparatorGenerator" />

      <show-association name="bpm:assignee" display-label-id="newAssignee"/>

   </property-sheet>
</config>
…

<config evaluator="node-type" condition="new:asingTask2" replace="true">
   <property-sheet>
      <separator name="sep1" display-label-id="general" component-generator="HeaderSeparatorGenerator" />
      <show-property name="bpm:workflowDescription" component-generator="TextAreaGenerator" display-label-id="newDescription"/>
      <show-property name="bpm:workflowPriority" display-label-id="newPriority"  />
      <separator name="sep2" display-label-id="users_and_roles" component-generator="HeaderSeparatorGenerator" />
      
      <show-association name="bpm:assignee" display-label-id="newAssignee"/>
   
    </property-sheet>
</config>

‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Am I being clear enough? I expect it to work for you too! =D

Roseta ,

I have modify my code as your ,but ,the problem still exist.I can not see any information under " General " ,such as Description,Review Priority,DueDate ect. where is wrong and what need I fix?
