Process Definition!
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>
Task Definition – Start Task cont.!<aspect name="dcwkflw:details">! <properties>! <property name="dcwkflw:abstract">! <type>d:text</type>! </property>! <property name="dcwkflw:duration">! <type>d:int</type>! </property>! </properties>! <associations>! <association name="dcwkflw:presenter”>! <source>…</source>! <target>! <class>cm:person</class>! <mandatory>true</mandatory>! <many>false</many>! </target>! </association>! </associations>!</aspect>!
Task Definition – Review Task!<type name="dcwkflw:presentationReviewTask"> <parent>bpm:activitiOutcomeTask</parent> <properties> <property name="dcwkflw:reviewOutcome"> <type>d:text</type> <default>Reject</default> <constraints> <constraint ref="dcwkflw:choices" /> </constraints> </property> </properties> <overrides> <property name="bpm:outcomePropertyName"> <default> {http://www.alfresco.org/model/dcworkflow/1.0}reviewOutcome </default> </property> </overrides> <mandatory-aspects><aspect>dcwkflw:details</aspect></mandatory-
aspects> </type>
Task Definition – Review Task cont.!<constraint name="dcwkflw:choices" type="LIST"> <parameter name="allowedValues"> <list> <value>Publish</value> <value>Reject</value> </list> </parameter> </constraint>
Deployment!
Spring: your-context.xml!<bean id="devconWorkflowBootstrap" parent="workflowDeployer"> <property name="workflowDefinitions"> <list> <props> <prop key="engineId">activiti</prop> <prop key="location">alfresco/extension/devcon-workflow.bpmn20.xml</prop> <prop key="mimetype">text/xml</prop> <prop key="redeploy">false</prop> </props> </list> </property> <property name="models"> <list><value>alfresco/extension/devcon-workflow-model.xml</value></list> </property> <property name="labels"> <list><value>alfresco/extension/devcon-workflow-model</value></list> </property> </bean>
Workflow Console!
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>
Task Form!<config evaluator="task-type" condition="dcwkflw:presentationReviewTask"> <forms> <form> <field-visibility> … <show id="dcwkflw:abstract" /> <show id="dcwkflw:duration" /> <show id="dcwkflw:presenter" /> <show id="dcwkflw:reviewOutcome" /> </field-visibility> <appearance> … <field id="dcwkflw:reviewOutcome”> <control template="/org/.../workflow/activiti-transitions.ftl" /> </field> … </appearance> </form> </forms> </config>
Workflow Details Form!
Workflow Details Form!<config evaluator="task-type” condition="dcwkflw:submitPresentationReviewTask"> <forms> <form id="workflow-details"> <field-visibility> <show id="bpm:sendEMailNotifications" /> <show id="dcwkflw:abstract" /> <show id="dcwkflw:duration" /> <show id="dcwkflw:presenter" /> <show id="packageItems" /> </field-visibility> <appearance>…</appearance> </form> </forms> </config>
Engine!
• Disabling • system.workflow.engine.jbpm.enabled=true!• system.workflow.engine.activiti.enabled=true!
• Definition Visibility • system.workflow.engine.jbpm.definitions.visible=false!• system.workflow.engine.activiti.definitions.visible=true!
• Override in alfresco-global.properties • Values shown in Admin Console or JMX Dump
Demo!
• Start ‘DevCon Presentation Review’ Workflow • Manage Task • Monitor Progress • Workflow Details!• Workflow Console!
