Hi everyone,I have following functionality... There is one workflow which is started on the document and will be assigned to one user group. Any member of that group will claim the task for review purpose. He/She will check the document and its properties (in wf task form) and will do following task

Hello,

In the platform side you need to extend the workflow content model of the task in which you want to select the group to add a new association with a cm:authorityContainer to store the approver.

            <associations>
                <association name="scwf:grouprevisor">
                    <source>
                        <mandatory>false</mandatory>
                        <many>false</many>
                    </source>
                    <target>
                        <class>cm:authorityContainer</class>
                        <mandatory>true</mandatory>
                        <many>false</many>
                    </target>
                </association>
            </associations>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

and must change workflow definition asigning the group selected to the task you want:

<userTask .... activiti:candidateGroups="${scwf_grouprevisor.properties.authorityName}" ... >
...
</userTask>
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

In the share side you need to change the form for the user task to show the groups selector:

    <config evaluator="string-compare" condition="....">
      <forms>
         <form>
            <field-visibility>
               ...
               <show id="scwf:grouprevisor" />
               ...
            </field-visibility>
            <appearance>
               ....
               <field id="scwf:grouprevisor" label-id="workflow.field.review_group" set="assignee" />
              ....
            </appearance>
         </form>
      </forms>
    </config>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Hi Roberto,

I sincerely appreciate your valuable inputs. I am still bit confused as this is something I'm exploring for the very first time. I would like to know what will this do? Basically our requirement is that if something is wrong with the document or properties, new assignee(group) will be selected from the user task form and task will go to that selected assignee(group), otherwise task will be submitted without selecting new assignee(group) and it will go to the next user in the hierarchy. Will it work like this?

Thanks

This configuration let you to select the user group in the review task form. I asume that you have define two custom outcomes that let you chose between the two paths in this point.

To define this in the platform side you need to extend the workflow content model of the task to add the definitión of this outcomes:

<properties>
    <property name="scwf:reviseOutcome">
        <type>d:text</type>
        <default>Ok</default>
        <constraints>
            <constraint type="LIST">
                <parameter name="allowedValues">
                    <list>
                        <value>Revise</value>
                        <value>Ok</value>
                    </list>
                </parameter>
            </constraint>
        </constraints>
    </property>
</properties>
<overrides>
    <property name="bpm:packageItemActionGroup">
        <default>edit_package_item_actions</default>
    </property>
    <property name="bpm:outcomePropertyName">
        <default>{http://www.someco.com/model/workflow/1.0}reviseOutcome</default>
    </property>
</overrides>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

In the workflow definition you must handling this custom outcomes in a listener for the complete event:

        <extensionElements>
	        <activiti:taskListener event="complete" class="org.alfresco.repo.workflow.activiti.tasklistener.ScriptTaskListener">
	          <activiti:field name="script">
                  <activiti:string>if(task.getVariableLocal('scwf_reviseOutcome') == 'Revise') {
					execution.setVariable('scwf_revise', true);
					} else {
					execution.setVariable('scwf_revise', false);
					}
                  </activiti:string>
              </activiti:field>
            </activiti:taskListener>
        </extensionElements> 
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

You must copy in an execution variable the outcome to use it in path selection. You can add here a control to ensure that the user group have been selected if you haven't mark it as required. Anyway you need to add to transitions from this task and use the execution variable to decide wich one take:

<sequenceFlow id='flow12' sourceRef='usertask3' targetRef='reviewDecision' />

<exclusiveGateway  id="reviewDecision" name="Review Decision" />     

<sequenceFlow id="flow13" sourceRef="reviewDecision" targetRef="usertask5">
        <conditionExpression xsi:type="tFormalExpression"><![CDATA[${scwf_revise == true}]]></conditionExpression>
</sequenceFlow>
<sequenceFlow id="flow14" sourceRef="reviewDecision" targetRef="usertask6">‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

In the share side you need to change the form definition for the user task to show the custom outcomes:

    <config evaluator="string-compare" condition="....">
      <forms>
         <form>
            <field-visibility>
               ...
               <show id="scwf:approveRejectOutcome" />
               ...
            </field-visibility>
            <appearance>
              ....
              <field id="scwf:approveRejectOutcome" set="response" />
              ....
            </appearance>
         </form>
      </forms>
    </config>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Hi Roberto Gamiz Sanchez‌

After break I have resumed working on this module. I am able to select group from wf task form but I am unable to assign task to that group.

<userTask id="demoWorkflowTask2" name="Demo Workflow First Task" activiti:candidateGroups="${dr_grouprevisor.properties.authorityName}"
activiti:formKey="dr:demoWorkflowTask2">
</userTask>

Above is how I have assigned the task to that selected group.

Below is the screenshot of the error I'm getting.

Can you please help me to fix this issue?

Thanks

Hello, I'm sorry I forgot a little step.

In the task where you choose the group you must to copy in an execution variable the group selected in order to use it later in the workflow:

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