WebService API: Renaming Folders

robobot

Urgent Problem. I have the following code to rename a folder.

 /**
     * folderPath e.g. /app:company_home/app:user_homes/cm:Main/cm:Users/cm:Bewerber/cm:Hancock_Paul
     * newFoldername e.g. Hancock_Herbie
     */
    public static void updateFolderName (String folderPath, String newFoldername){

     UpdateResult [] result = null;  
     //get the reference to the data which should be updated
     final Reference reference = new Reference(STORE, null, folderPath);     
     final Predicate p = new Predicate(new Reference[]{reference},STORE,null);

     //create CMLUpdate instance referring to the current data
     final CMLUpdate updateFolder = new CMLUpdate( new NamedValue[]{Utils.createNamedValue(Constants.PROP_NAME, newFoldername)},p,null);
     
     CML cml = new CML();
     cml.setUpdate(new CMLUpdate[]{updateFolder});
     try {
       result = WebServiceFactory.getRepositoryService().update(cml);       
       // still the old path!
       System.out.println("new path: "+result[0].getDestination().getPath());       
     } catch ( RepositoryFault rf ) {
       rf.printStackTrace();
     } catch ( RemoteException re ) {
       re.printStackTrace();
     }     
    }

May anybody help me, why does sysout not print what i am expecting? when i look in alfresco, the folder has been successfully renamed!
Thank you very much for any advice!

may somebody please give me a short hint ?
still don't know how to manage this.

Some more details of what you were getting from your System.out seeing may have helped.

There's two "name" fields and you are changing the "display name" of the node which is a multilingual property. The display name will not affect the "path" of the node which is based on the association name.

robobot

The sysout still prints the old Path after the update

/app:company_home/app:user_homes/cm:Main/cm:Users/cm:Bewerber/cm:Hancock_Paul
‍‍‍

i excepted the new path

/app:company_home/app:user_homes/cm:Main/cm:Users/cm:Bewerber/cm:Hancock_Herbie
‍‍‍

i am sure your hint is useful. but which is the right property to be set here ?

new NamedValue[]{Utils.createNamedValue(Constants.PROP_NAME, newFoldername)}
‍‍‍

I'm not that familiar with the WebService API but a casual inspection suggests you probably want to use CMLMove rather than CMLUpdate. Since it is the association name between your document's parent and your document that you want to change not a property of your document.

robobot

Thank you for your message. It seems, that using CMLMove does not solve my problem. here is a complete example taken from

The root problem is, that the documents can not be found any more, after a space name was changed, because i am using path queries to find documents in a specific folder. a path query does not work after the folder update

+PATH:/app:company_home/app:user_homes/cm:Users/cm:Candidate/cm:NEW
‍‍‍

Failed to resolve to a single NodeRef with parameters (store=workspace:SpacesStore uuid=null path=/app:company_home/app:user_homes/cm:Users/cm:Candidate/cm:NEW), found 0 nodes.</ns1:message>
