Advanced workflow

liso — Thu, 22 Sep 2011 14:54:41 GMT

I created and uploaded processdefinition using jbpm. I also add: <type name="wf:iniApp"> <parent>bpm:startTask</parent> <mandatory-aspects> <aspect>bpm:assignee</aspect> </mandatory-aspects> </type>‍‍‍‍‍‍In

hi Liso,

I think some thing miss or mistake in name space tag of your model file. Check it once.

If you post your model and process definition file, some one can help you, without those finding the error very difficult.

I created a workflow using JBPM and it generated the following process defenition file. I deployed process definition using JBPM.

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

<process-definition  xmlns="urn:jbpm.org:jpdl-3.2"  name="Vehicle Process4">

   <swimlane name ="initiator"/>
   
   <start-state name="initiate">

       <task name="wf:initApp" swimlane="initiator">

      <transition to="supervisor" name="to supervisor"></transition>
   </start-state>
  <swimlane name="assignee">
    <assignment actor-id="#{bpm_assignee.properties['cm:userName']}"/>
  </swimlane>
   

    <swimlane name ="c pule"/>
   
    <task-node name="supervisor">

Hi Liso

It is bad practice to change the files under webapps and not a good idea to change the alfresco workflow model.

Create a new model file for yourself (see example below) and deploy this model (I assume that you know how to do that). Re-instate the Alfresco workflow model to what it was and then let's try it again.

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

<model name="wfge:workflow-green-energy" xmlns="http://www.alfresco.org/model/dictionary/1.0">

    <description>Green Energy Workflow Model</description>
    <author>Alfresco Training</author>
    <version>1.1</version>

   <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.alfresco.org/model/training/1.0" prefix="wfge"/>
   </namespaces>

   <types>

      <type name="wfge:startSopReview">
         <parent>bpm:startTask</parent>
         <mandatory-aspects>
         <aspect>wfge:instructionAspect</aspect>
         </mandatory-aspects>

         <aspect>wfge:commentAspect</aspect>
         <aspect>wfge:instructionAspect</aspect>         
         </mandatory-aspects>
      </type>
      
   </types>
   
   <aspects>

      <aspect name="wfge:instructionAspect">
         <properties>
             <property name="wfge:instructions">
                <type>d:text</type>
                <mandatory>true</mandatory>
             </property>
         </properties>
      </aspect>
      
      <aspect name="wfge:commentAspect">

             <property name="wfge:comment">

                <mandatory>false</mandatory>
             </property>
         </properties>
      </aspect>      

   </aspects>

</model>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍
