[xwiki-devs] Looking for help with groovy

24 Mar 2014


      I am trying to modify the following code so when the user enters a new
documentName, it will set the title and rename the document.  If I uncomment
the saveDocument line, it works.  So I know the rest of the code is working. 
Can anyone see what I am doing wrong?

{{groovy}}
import org.xwiki.observation.*
import org.xwiki.observation.event.*
import org.xwiki.bridge.event.*
import org.xwiki.context.*
import com.xpn.xwiki.web.*
import com.xpn.xwiki.*
import org.apache.velocity.VelocityContext;

class ProcessDocumentRenamer implements EventListener
{
    def xwiki
    def context
  
    ProcessDocumentRenamer(xwiki, context)
    {
        this.xwiki = xwiki
        this.context = context
    }

    String getName()
    {
        // The unique name of this event listener
        return "ProcessDocumentRenamer"
    }

    List<Event> getEvents()
    {
        // The list of events this listener listens to
        return Arrays.asList(new DocumentCreatedEvent(), new
DocumentUpdatedEvent())
    }

    // Called by the Observation Manager when an event matches the list of
events returned
    // by getEvents()
    void onEvent(Event event, Object source, Object data)
    {
        // Current context
        def crtContext =
Utils.getComponent(Execution.class).getContext().getProperty('xwikicontext')

        // Defines the type of object that should be looked for
        def myObject =
source.getObject("DocumentationTemplates.ProcessClass");

        // If the page has an object of the specified class, we get the
value of the relevant property and assign it to our documentName variable
        if (myObject != null) {
          // Defines the variable that we will later use to update the title
of the document
          def documentName = myObject.get("processName").value
          // Defines the Complete name we will use later when we rename the
document.
          def FullDocumentName = source.getWikiName() + "!" +
source.getSpaceName() + "." + documentName;
          // If the name has changed, we need to update and rename the
document.
          if (source.getName() != documentName) {
            source.setTitle(documentName)
            // Force the storage to keep the same version number, so that
this looks like a single save event
            source.setMetaDataDirty(false);
            source.setContentDirty(false);
            // crtContext.getWiki().saveDocument(source,
source.getComment(), source.isMinorEdit(), crtContext);

            crtContext.getWiki().renamePage(source, FullDocumentName);
          }
        }        
    }
}

// Register against the Observation Manager
def observation = Utils.getComponent(ObservationManager.class)
observation.removeListener("ProcessDocumentRenamer")
def listener = new ProcessDocumentRenamer(xwiki, xcontext)
observation.addListener(listener)
{{/groovy}}
