jPDL process design strategy to ease portability to Activiti

Hi,We’re currently implementing an Alfresco project with a particular emphasis on process modeling which, due to our release timescales, is targeted at Alfresco 3.x and therefore jBPM/jPDL. Given the imminent move of Alfresco to Activiti/BPMN2.0 in future releases, we’d like to ensure that we make i

I can give you an answer on 3):

Activiti in Alfresco will also support using the Alfresco-scripting. Simmilar to the AlfrescoJavaScript, there are TaskListeners and ExecutionListeners available that execute alfresco-javascript. This is done exactly the same way as with JBPM, exposing root-objects (eg. nodeService, people) to be used.
eg:


 <extensionElements>
              <activiti:executionListener event="start" class="org.alfresco.repo.workflow.activiti.listener.ScriptExecutionListener">
           <activiti:field name="script">
                      <activiti:string>
                         var members = people.getMembers(bpm_groupAssignee);
                         var memberNames = new java.util.ArrayList();
                         
                         for(var i in members) {
                          memberNames.add(members[i].properties.userName);
                         }
                         execution.setVariable('wf_groupMembers', memberNames);
                         execution.setVariable('wf_reviewerCount', memberNames.size());
                      </activiti:string>
                   </activiti:field>
             </activiti:executionListener>
          </extensionElements>

Since Activiti uses JSR-233 for it's scripting (and script-task), currently it's not possible to use Alfresco Javascript from within a BPMN ScriptTask. However, you can use scripting on the NodeRefs (eg. initiator.properties.userName etc) in JSR-233 environment. But to have full alfresco-js-support, a custom service-task should indeed be used.
