Re: [rules-users] Eval0Invoker : java.lang.NullPointerException
Do the problematic rules work in isolation? i.e. if you try them
individually in a KnowledgeBase.
What if you try the problem rules without the eval? e.g.:-
rule "PAN Device MAC Address null or empty rule"
no-loop true
salience 200
when
$customer : Customer()
$esis : ElectricServiceInterface() from
$customer.getElectricServiceInterfaces()
$panDevice : PANDevice( MACAddress == null || == "" ) from
$esis.getPANdevices()
then
throw new MissingEntryFault("MAC Address cannot be null or
empty");
end
Also, don't get runtime NPE's confused with design-time NPE's (such as the
RETE viewer in Eclipse).

Hi Manstis, PANDevice is not null, instead I am setting the value of
"macAddress" using this object. So how can it be null, I am initializing
this object.
Also, as I said, the last two rules works fine for null value, but not the
three before those. which are below rules
PAN Device MAC Address null or empty rule
PAN Device Install Code null or empty rule
For the above two rules, I am checking for "empty" value in my test case.
PAN Device Smart Device Model null rule
Also, in the Eclipse, when I am going to "Rete" tab it is showing this
error,
"Unable to parse rules to show RETE view! null"
I guess the null pointer exception is screwing everything.
Thanks,
Venkat.
