Re: [rules-users] Null pointer when inserting into working memory
I've never seen this error before. Did you tried Drools 5? The error
still happens? Can you recreate in a junit test case?

Hi all,
Using 4.0.7.
I am getting this null pointer when doing an Insert into working memory.
I know the object I am inserting is not null.
java.lang.NullPointerException

Any idea what might be causing this?
