Re: [rules-users] problem escaping quote in eval

Hello, I'm trying to construct a rule in drool V4 that contains and eval and a literal string that may contain quotes. I've tried escaping the quote but get the error below. The \" works outside an eval. rule "evalList2" when Var( eval( "tt".equals("t\"t"))) then System.out.println( "evalList2" ); end Error: java.lang.NullPointerException: at org.drools.rule.PredicateConstraint.createContextEntry(PredicateConstraint.java:201) at org.drools.reteoo.AlphaNode.createMemory(AlphaNode.java:230) ... It looks like a change was made to V3 to fix this but doesnt appear to work in V4, does anyone know how to construct this type of rule?
