Re: [xwiki-users] Dynamically set rights over document

28 Feb 2011

      Hi,

Thank you for the reply!

I'm trying to implement the groovy listener but I'm doing something wrong..

This is what I'm trying to do:

{{groovy}}
import org.xwiki.observation.*
import org.xwiki.observation.event.*
import com.xpn.xwiki.web.*
import com.xpn.xwiki.*

class RightsEventListener implements EventListener
{
    def xwiki
    def context
    def doc

    RightsEventListener(xwiki, context, doc)
    {
        this.xwiki = xwiki
        this.context = context
        this.doc = doc
    }

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

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

    // Called by the Observation Manager when an event matches the list of
events returned
    // by getEvents()
    void onEvent(Event event, Object source, Object data)
    {
        def rightsObject = doc.getObject("XWiki.XWikiRights", true)
        rightsObject.set("groups", "")
        rightsObject.set("levels", "edit")
        rightsObject.set("users", "Luis Braga")
        rightsObject.set("allow", 1)
        doc.save()
    }
}

// Register against the Observation Manager
def observation = Utils.getComponent(ObservationManager.class)
observation.removeListener("dynamicRights")
def listener = new RightsEventListener(xwiki, xcontext, doc)
observation.addListener(listener)

{{/groovy}}

When I update the file I get an error:

For my surprise the XWikiRights object is created but don't work. If I
create the exactly same object manually it works.
