Mondrian/Saiku - Closure Table - Null Pointer Exception

Question

I am currently doing a PoC and facing a problem with closure table. I am using Saiku CE and database is postgres. Everything works until I add a closure table. If I remove closure table hierarchy, I don't get any error. If keep it I get the error. I have created my demo schema using Foodmart.xml which I downloaded from Saiku itself.

Some forums suggested that it's an open bug with Mondrian but if it is then why same syntax works with foodmart? Is it a problem with Saiku CE? If I use Saiku EE (Trial version) for my PoC then will it work?

Managed to fix this issue. Dimension definition was correct however dimension with closure table should be declared within the cube. If you declare them outside of the cube you would get this idiotic error. Looks like a bug with Mondrian 4.
