Hi,

I would like to execute specific rules from the rule file(.xml). Find the rule file content below. There are three rules are available in the xml file(Rule names: 1.Check_NotNullof_rfqId , 2.Check_NotNullof_partId and 3.validateFullName)

First time we are trying to execute 1.Check_NotNullof_rfqId and 2.Check_NotNullof_partId rules. next time we are trying to execute 3.validateFullName rule

We have tried the following option

The rule name start with "Check" require to set only "rfq" global identifier.

So when we execute first two rules we followed following approach

workingMemory.setGlobal("rfq",rfqbean);

workingMemory.fireAllRules(new RuleNameStartsWithAgendaFilter( "Check" ));

but it gives following NullPointerException. It is trying to execute validatefullname rule also.

Caused by: java.lang.NullPointerException
at rules.Rule_Check_NotNullof_rfqId_0.eval0(Rule_Check_NotNullof_rfqId_0.java:9)
at rules.Rule_Check_NotNullof_rfqId_0Eval0Invoker.evaluate(Rule_Check_NotNullof_rfqId_0Eval0Invoker.java:16)
at org.drools.rule.EvalCondition.isAllowed(EvalCondition.java:71)
... 12 more

When we execute third rule alone. we followed following approach

workingMemory.setGlobal("loanApplication",loanApplicationbean);

workingMemory.fireAllRules(new RuleNameStartsWithAgendaFilter( "validate" ));

Please help us to resolve this issue
