[CDO] CDO Workspace fetches proxy elements [message #903965]

Hey there,

I am using CDO Workspace with 4.1-SR1-RC1 (S20120821-0638). I perform the following steps:

First, I check out the main branch of the repository (should work --> no exceptions).
Then, I access the root element which also works fine. But, it seems as if the children of the root were not fetched into the local workspace. There are only elements of the type CDOElementProxy.

I remember that it has already worked in a previous version. Is there a known issue or am I missing some configurations?

Greetz,
Tino

Hi Tino,

I can't remember any major changes in the CDOWorkspace framework. What IStore implementation are you using and how are
you setting up your local CDOSession?

Cheers
/Eike

Hi Eike,

thanks for your quick reply.

I am using the DBStore implementation with the H2 adapter. Today, I recognized that everything works fine if I remove the CDOCollectionLoadingPolicy (http://wiki.eclipse.org/Tweaking_CDO_Performance).

CDOCollectionLoadingPolicy policy = CDOUtil.createCollectionLoadingPolicy(0, 300);
session.options().setCollectionLoadingPolicy(policy);

What do you think?

Cheers,
Tino

In your first post you haven't said what was not working fine. You've just described soem internal state of EMF/CDO, not
that that leads to an evident problem.

> CDOCollectionLoadingPolicy policy = CDOUtil.createCollectionLoadingPolicy(0, 300);
Indeed, this policy with initialChunkSize=0 leads to lists that are initially populated with proxy elements only.
Increasing the initialChunkSize should change that. But, as I said above, the actual Java objects in the lists are an
implementation detail and if they're proxies they should be resolved when you access them.

Hi Eike,

sorry that I did not state my problem clearly. I seems to be that the proxies are not resolved when I access them. If I remove the policies, it works. But we will also keep on our investigation.

Cheers,
Tino
