Subject Internal error while retrieving nt:file node
Date Thu, 15 May 2008 19:51:46 GMT
Hello all,

I have a use case where I copy a subtree to a new location within the same workspace using
Workspace.copy(..). This subtree contains nt:file nodes. When I try to access the file nodes
in the "source" subtree afterwards, I get the "internal error" logger message in the bottom
of this mail. The "destination" subtree is not throwing any errors.

However, this only happens in my production environment. I have written a test to try to expose
the problem, but am unable to reproduce the bug. Since the only difference between my test
environment and my production environment is the database, I tried to run the test up against
my production environment to see if it was a Postgres bug, but to no avail.

My test environment uses the H2PersistenceManager, while my production environment uses the
PostgreSQLPersistenceManager. I am not using the DataStore.

Can someone enlighten me on what might be the cause of this internal error? It's hard to debug
this when I have no idea of what's going on.

Best regards,
Karianne Berg
