[ https://issues.jboss.org/browse/JBRULES-3215?page=com.atlassian.jira.plug... ] Edson Tirelli edited comment on JBRULES-3215 at 10/3/11 11:22 AM: ------------------------------------------------------------------ Jean-Marc, I tried your example with the latest Drools master branch code and it no longer raises a NPE. It now provides an error message: {code:title=ErrorMessage.txt|borderStyle=solid} Unable to create reader for 'reference.source':[Error: unable to resolve method using strict-mode: java.lang.Object.source()] [Near : {... reference.source ....}] ^ [Line: 1, Column: 0] : [Rule name='form-rules.n3 9'] [Error: unable to resolve method using strict-mode: java.lang.Object.source()] [Near : {... reference.source ....}] ^ [Line: 1, Column: 11] Rule Compilation error : [Rule name='form-rules.n3 9'] n3_project/helpers3/Rule_form_rules_n3_9.java (30:2567) : $JTEXT_FIELD cannot be resolved {code} This happens because Drools 5.2 implemented tighter compile time type checking. Since Assignment.reference is a java.lang.Object, the engine is unable to check that the actual instance in there contains a property named "source". To disable compile time type checking for the Assignment class you can use a declare statement: declare Assignment @typesafe( false ) end This way Drools will not try to resolve "source" at compile time, but instead will resolve it dynamically at runtime. I don't have your full code to test your rule above, but with the declare, it does successfully compiles. was (Author: tirelli): Jean-Marc, I tried your example with the latest Drools master branch code and it no longer raises a NPE.
