Example Process Definition!

Start Task!<process id="presentationReview” name="DevCon Presentation Review">

<startEvent id="start” activiti:formKey="dcwkflw:submitPresentationReviewTask" />

<sequenceFlow id='flow1' sourceRef='start' targetRef='reviewTask' />

Review Task!<userTask id="reviewTask" name="Review Presentation" activiti:formKey="dcwkflw:presentationReviewTask"> <extensionElements> <activiti:taskListener event="create" class="org.alfresco.repo.workflow.activiti.tasklistener.ScriptTaskListener"> … </activiti:taskListener> <activiti:taskListener event="complete" class="org.alfresco.repo.workflow.activiti.tasklistener.ScriptTaskListener"> <activiti:field name="script"> <activiti:string> execution.setVariable('dcwkflw_reviewOutcome', task.getVariable('dcwkflw_reviewOutcome')); </activiti:string> </activiti:field> </activiti:taskListener> </extensionElements> <humanPerformer> <resourceAssignmentExpression> <formalExpression>${bpm_assignee.properties.userName}</formalExpression> </resourceAssignmentExpression> </humanPerformer> </userTask>

Decision!<sequenceFlow id='flow2' sourceRef='reviewTask' targetRef='reviewDecision' />

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

<sequenceFlow id='flow3' sourceRef='reviewDecision' targetRef='approved' > <conditionExpression xsi:type="tFormalExpression"> ${dcwkflw_reviewOutcome == 'Publish'} </conditionExpression> </sequenceFlow>

<sequenceFlow id='flow4' sourceRef='reviewDecision' targetRef='rejected' />

Approved Task!<userTask id="approved" name="Presentation Approved"

activiti:formKey="wf:approvedTask" > <extensionElements> <activiti:taskListener event="create” class="org.alfresco.repo.workflow.activiti.tasklistener.ScriptTaskListener"> … </activiti:taskListener> </extensionElements> <humanPerformer> <resourceAssignmentExpression> <formalExpression>${initiator.properties.userName}</formalExpression> </resourceAssignmentExpression> </humanPerformer> </userTask>

Rejected Task!<userTask id=”rejected" name="Presentation Rejected"

activiti:formKey="wf:rejectedTask" > <extensionElements> <activiti:taskListener event="create” class="org.alfresco.repo.workflow.activiti.tasklistener.ScriptTaskListener"> … </activiti:taskListener> </extensionElements> <humanPerformer> <resourceAssignmentExpression> <formalExpression>${initiator.properties.userName}</formalExpression> </resourceAssignmentExpression> </humanPerformer> </userTask>

Task Definition!

Based on Alfresco Content Modelling!

• bpmModel.xml • bpm:task!• bpm:workflowTask!• bpm:startTask!• bpm:activitiStartTask!• bpm:activitiOutcomeTask!

• workflowModel.xml • wf:submitAdhocTask!• wf:reviewTask!• wf:activitiReviewTask!• wf:approvedTask!

Start Task!<type name="dcwkflw:submitPresentationReviewTask"> <parent>wf:submitReviewTask</parent> <mandatory-aspects> <aspect>dcwkflw:details</aspect> </mandatory-aspects> </type>

Configuration!

UI – Hiding Workflows!<config evaluator="string-compare" condition="Workflow"> <hidden-workflows> <!-- Hide all WCM related workflows --> <workflow name="jbpm$wcmwf:*"/> <workflow name="jbpm$wf:articleapproval"/> </hidden-workflows> </config>

UI – Hiding Tasks!<config evaluator="string-compare" condition="Workflow"> <hidden-tasks> <!-- Hide all WCM related tasks --> <task type="wcmwf:*"/> </hidden-tasks> </config>

Start Workflow Form!<config evaluator="string-compare" condition="activiti$presentationReview"> <forms> <form> <field-visibility> <show id="bpm:workflowDescription" /> <show id="bpm:workflowDueDate" /> <show id="bpm:workflowPriority" /> <show id="bpm:assignee" /> <show id="dcwkflw:abstract" /> <show id="dcwkflw:duration" /> <show id="dcwkflw:presenter" /> <show id="packageItems" /> <show id="bpm:sendEMailNotifications" /> </field-visibility> <appearance>…</appearance> </form> </forms> </config>
