Hi,
I am going to explain more precisely what i would like : for one
CDOObject, i want its commits history, for example if i have an object
"object1", the result can be:
Revision version | commit message | commit user ID
1 | object1 creation | user1
2 | object1 renaming | user2
With the CDORevisionManager, i have access to all the "last" revisions
of the objects (in my example the version 2 commit) but i do not find
the older versions (in my example the version 1 commit).
The method CDOUtil.getRevisionByVersion gets a revision for only one
version. Do i have to get all the versions and iterate on them to have
all the revision of my object or have you another solution ?
I also try CDOCommitInfoManager.getCommitInfos but i do not know how to
link the commit infos to a CDOObject.
Thanks
Nathalie.

I must be misunderstanding something. Why do you think that, with the methods I suggested, you can not retrieve "older"
revisions of an object? Perhaps you've not configured your repository for auditing so that these old revisions are not
kept at all? Please see http://wiki.eclipse.org/CDO/Server_Configuration_Reference#Property_supportingAudits in this case.
Please also note that you can not use CDORevisions like EObjects. While some data types (String, primitives, some more)
are treated in the same way, others are not and would need special conversion by you. All references are a good example,
as the CDORevision does only deliver the CDOID of the target objects and you'd have to use the revision manager to
retrieve the target revisions manually. Whenever you expect EMF standard behviour for objects it's best to use a CDOView
to automatically construct the object graph of a particular time in a particular branch.

CommitInfos represent the changes to objects that were contained in particular commits, expressed in CDORevisions for
added objects, CDORevisionDeltas for changed objects and CDOIDs for deleted objects. A repository supporting audits is a
precondition, of course. If you want to reconstruct the EObjects from that (commit) time and branch you'd open an audit
CDOView, e.g., CDOSession.openView(commitInfo).
Does that help?
