Making my first steps with Documentum, so please bear with me. Using DFS .NET productivity layer, I'd like to rename a folder in the repository. What I do is basically: * Create an identity using the current folder path * Create a property filter, and have it include only the object_name property * Create a PropertySet, and set the new name to object_name * Run the IObjectService.Update() As a result, the folder name is indeed changed. However, the Update never returns. Instead, it throws a FaultException (wrapped in a ServiceInvocationException) which says: "Update" operation failed for object: [ ] [id = ] PROPERTIES [object_name= ]. where is the new object_name and is the original path. What am I doing wrong here? How come the action succeeds but I still get an error? How can I further investigate this? Thanks, Eran

Renaming a folder using DFS succeeds but throws. Why?

Making my first steps with Documentum, so please bear with me.

Using DFS .NET productivity layer, I'd like to rename a folder in the repository. What I do is basically:

Create an identity using the current folder path
Create a property filter, and have it include only the object_name property
Create a PropertySet, and set the new name to object_name
Run the IObjectService.Update()

As a result, the folder name is indeed changed. However, the Update never returns. Instead, it throws a FaultException (wrapped in a ServiceInvocationException) which says:

"Update" operation failed for object: [<new name>] [id =<old path>] PROPERTIES [object_name=<new name>].

where <new name> is the new object_name and <old path> is the original path.

What am I doing wrong here? How come the action succeeds but I still get an error? How can I further investigate this?

Thanks,

Eran

seems like a DFS bug. you can use ObjectId instead of ObjectPath. it's always best practice you call ObjectService.Get() first to get the objects and then set some properties for them, then call Update() to set these properties permanently.

btw, there is something wrong with your code. if I'm not wrong, OperationOptions doesn't provide such interface.

OperationOptions operationOptions = new OperationOptions(propertyProfile);

You can view the DFS server log for what's the roor cause for your error.

For example,DFS related log for JBoss Server can be found at like C:\Documentum\jboss4.2.0\server\DctmServer_MethodServer\log.

That will be helpful to debug if you can post the detailed error message and your test code.

which version of DFS do you use? Maybe you can post here your code snippet.

Thank you WangTodd and zhou_simonq.

I'm using recently downloaded Documentum 6.5. Here's the source code, slightly modified for brevity:

ObjectPath objPath = new ObjectPath("/cab/folder1");

ObjectIdentity objId = new ObjectIdentity(objPath, "the_repository");

PropertyProfile propertyProfile = new PropertyProfile(PropertyFilterMode.ALL_NON_SYSTEM);

OperationOptions operationOptions = new OperationOptions(propertyProfile);

DataObject dataObject = new DataObject(objId);

dataObject.Properties = new PropertySet();

dataObject.Properties.Set("object_name", "folder2");

// this changes the object name but throws an exception

objSvc.Update(new DataPackage(dataObject), operationOptions);

The error snippet, as found in the jBoss log, is:

2009-12-10 08:52:43,802 ERROR [STDERR] 10/12/2009 08:52:43 com.sun.xml.ws.server.sei.EndpointMethodHandler invoke

INFO: "Update" operation failed for object: [folder2] [id =/cab/folder1] PROPERTIES [object_name=folder2].

com.emc.documentum.fs.rt.SerializableException: "Update" operation failed for object: [folder2] [id =/cab/folder1] PROPERTIES [object_name=folder2]. at com.emc.documentum.fs.services.core.ObjectServiceWebService.update(ObjectServiceWebService.java:86)

... and so on ...

Two other pieces of information:

1. I started with trying to rename folders, but renaming files yielded the exact failure

2. Renaming using DQL works without a problem

My hunch is that trying to change the name as a regular property somehow collides with the use of the name as an ID. Treating the name as yet another object propery does feel awkward, but I don't know how else can I do this. Hasn't anyone ever renamed an object?

Well, getting the object ID first did the trick. I was hoping to avoid the extra call, but renames aren't done that often, and I'd rather have code that works...

As for the OperationOption correction - you're right again. I've edited the code to make it shorter, and haven't bothered to make sure it compiled. That part of the code is not significant to the problem, so I got a little sloppy.

Thanks for the answer,
