[rules-users] Nullpointer inserting fact.

Hey, I ve got a class WebService{ getter/setter for invoke property } then i got the following rules rule "..." salience 10 when $web : WebService ( ) then Invoke inv = new invoke(); $web.setInvoke(inv); insert(inv); end this succeeds,but then the following rule : rule "..." salience 9 when $inv : Invoke( ) $web : WebService ( invoke == $inv); then ... end never gets executed,because he doesnt find a webservice with same invoke, (according to debug information,they are the same invoke object) Is it possible that this happens because when i inserted the webservice in the workingmemory, the invoke property was not yet defined(=null)? Does anyone know a solution for this?
