i have now tried an installation of dotlrn 2.3.1 + xowiki used outside of a community (as you sketched) in postgres, everything works as expected.

The problem appears to be different semantics in the OpenACS and Oracle versions of [fs::get_root_folder], when it is called with a package_id having no root folder. In PostgresSQL fs::get_root_folder -package_id 123 returns empty, while oracle throws apparently the error above.

I fixed the problem the easy way (in xowiki), a better fix would be to make the Postgres and Oracle versions of fs::get_root_folder to behave identical.

Best regards

Thanks a lot Gustaf.

I upgraded xowiki with your change and it works correctly.

I will install xowiki version for dotlrn 2.3.1 on oracle,I will test the upgrade to 0.90. I will post the result of this with logs.

I think that the problem with fs::get_root_folder is complicado to fix because I think that it's no only for this function. I will post it to try fix it

Sorry replace complicato with complicated.
