Creation of AVMUndoSandboxListAction like action

[rdifrango]

All,

I am trying to create an action that is exactly like the AVMUndoSandboxListAction class.  The only difference is that I am wrapping it in a Webscript call and acting as a proxy for the user.  Here is my code:

package org.hhmi.alfresco.webscript.wcm;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;

import org.hhmi.alfresco.javascript.Impersonation;
import org.hhmi.alfresco.utils.WcmUtils;

public class WcmUndoWorkflow extends DeclarativeWebScript {
   // Logger
   private static final Log logger = LogFactory
         .getLog("org.alfresco.repo.web.scripts");

   transient private ServiceRegistry services;

   public void setServices(ServiceRegistry services) {
      this.services = services;
   }

      String stagingStore = AVMUtil.buildStoreWebappPath(wcmUtils
            .getStagingStore(null), webapp);
      logger.info("RRD: stagingStore = " + stagingStore);

      //

The bizarre thing is that this worked just fine under the 3b, but does not under the Enterprise release.

Well, it seems as if in the released version you can no longer under changes to files that exist in the root directory of a web project.  I personally see this as a bug, but I would love to hear from an Alfresco person on this topic.

Just out of interest - is this still the case?
