Bit sorry that did not post this yesterday - now I know better - we could have avoided some duplication of work . I was stopped at the same error that you mention Lars after fixing porting stuff. Then, I saw this
Dave Bauer's fix for wp-slim-drop.sql . Commented these same lines from slide/presentation delete code and it works ! But not sure if this is *proper* thing to do :
-- update acs_objects set context_id=null where context_id = slide id;
Caroline,I am very hopeful of making Wimpy work for dotLRN - including Roger's suggestions if all agree. I don't know (yet) internals of ACS, but with all the excellent support from this vibrant community, it should be matter of only couple of weeks. Can't wait till .LRN is ready for Postgres.
