[rules-users] Newbie need help.

[mashup]

Hi Alan,

Just thought I would say I suffered from the same problem and found the
solution hidden in the manual somewhere. The tutorial needs updated....

use:
WorkingMemory workingMemory = ruleBase.newStatefulSession();

and

workingMemory.insert(obj); //instead of assert

cheers

Richard
