[LOGIC-37] The facts and retractions functions do not take the relation's namespace into account when resolving the index. Created: 03/May/12  Updated: 28/Jul/13  Resolved: 27/Sep/12

Patch: Code


Inserting facts into a relation that is defined in another namespace, specifically a namespace that has been required but not referred (I don't see the bug if I :use the other namespace).

I've tracked the problem down to this line:


In the facts function, when the relation index gets resolved, the namespace is not taken into account,

index (var-get (resolve (index-sym (.name rel) arity o)))

as it is when resolving the relation set.

rel-set (var-get (ns-resolve rel-ns (set-sym (.name rel) arity)))

Using ns-resolve, with rel-ns, seems to fix the issue for me.

index (var-get (ns-resolve rel-ns (index-sym (.name rel) arity o)))

Apologies for the slow response. Is this still a problem?

Hi David,

Nope, the problem has been resolved, as I recall you applied the patch and cut a new release the same day I submitted the request; so thanks again for the quick fix!
