Hello,

I would like to access the properties of the documents associated to a workflow. The problem is that I don't know how to retreive the nodes from the ExecutionContext…

The workflow load the java class :

<node name="notifyERP">
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<event type="node-enter">
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<action class="manageoffice.workflows.Demobase" />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</event>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<transition to="end1"></transition>
&nbsp;&nbsp;&nbsp;</node>
‍‍‍‍‍‍‍‍

The Java class :

public class Demobase implements ActionHandler, configurationModule {
   private static final Logger logger = Logger.getLogger(Demobase.class);
   private BeanFactory factory;
   public Demobase() {
      super();
   }

   @Override
   public void execute(ExecutionContext executionContext) throws Exception {
      if (logger.isDebugEnabled()) {
         logger.info("Will notified ERP Database");
      }
???
…
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

How can I get the nodes that where attached at the beginning of the Workflow ?

Thanks

The nodes that were attached to the workflow are placed in a process variable called "bpm_package". You can iterate over the children of that node from JavaScript written as part of the process definition, or in Java code, which is the route you've chosen.

The code would look something like:

ContextInstance contextInstance = executionContext.getContextInstance();
JBPMNode jbpmNode = (JBPMNode) contextInstance.getVariable("bpm_package"); // there might be a constant that has this somewhere
NodeRef packageNodeRef = jbpmNode.getNodeRef();
List<ChildAssociationRef> childRefList = nodeService.getChildAssocs(packageNodeRef);

for (ChildAssociationRef childAssocRef : childRefList) {
    // do something with each document in the workflow package
    NodeRef nodeRef = childAssocRef.getChildRef()
}‍‍‍‍‍‍‍‍‍
