When removing a Workflow Definitions, all workflowNames mentioning that definition should be updated

[maoo]

Create an AOP Listener that is notified everytime a Workflow undeployment occurs.

To take inspiration from existing code, check class NodeRefPropertyMethodInterceptor.java and its configuration in node-services-context.xml

<bean id="nodeRefPropertyInterceptor" class="org.alfresco.repo.node.NodeRefPropertyMethodInterceptor" init-method="init">
  <property name="nodeService">
    <ref bean="mlAwareNodeService" />
  </property>
  <property name="dictionaryService">
    <ref bean="dictionaryService" />
  </property>
</bean>

How to implement the logic:

• SiteService.listSites provides a way to fetch all (or filtered) Alfresco sites
  • if the method doesn't allow to filter for property rrdathena:workflowNames, it is possible to iterate on listSites results and post-filter
• For each site being returned, fetch the list of workflowNames, remove the workflow definition that have been un-deployed and save the property value again
