Forum OpenACS Development: Re: Compatibility Matrix
as Gustaf already mentioned in a previous post, the changes we made sometime ago were done in a way that switching back to the original implementation of permissions was done as easy as possible.
Therefore the code that I provided to you ( which can be found here: https://github.com/vguerra/permissions ) does not alter the current data model. By using recursive queries some tables and triggers are not necessary anymore but this is something we still have to do locally.
As soon as we make progress on that I'll provide the changes.
