[rules-dev] MVEL in functions?

[Michael Neale]

Hey is mvel in functions broken? I have a distant memory of something
along these lines. I was just trying something like:

package jboss.cloud

dialect "mvel"


#trying to get functions working...
rule "something"
    when
        s: SimpleFact(id == 42, name == "michael")
    then
        System.out.println("hello");
end

function String doSomething() {
 return "hey";
}

And I get:

java.lang.NullPointerException
	at org.drools.rule.builder.dialect.mvel.MVELDialect.compile(MVELDialect.java:510)
	at org.drools.rule.builder.dialect.mvel.MVELDialect.addFunction(MVELDialect.java:338)
	at org.drools.compiler.PackageBuilder.addFunction(PackageBuilder.java:1104)
	at org.drools.compiler.PackageBuilder.addPackage(PackageBuilder.java:626)
	at org.drools.compiler.PackageBuilder.addPackageFromDrl(PackageBuilder.java:290)
	at org.drools.compiler.PackageBuilder.addKnowledgeResource(PackageBuilder.java:488)
	at org.drools.builder.impl.KnowledgeBuilderImpl.add(KnowledgeBuilderImpl.java:25)

(haven't tried trunk) - anyone else seen this?
removing the dialect "mvel" at the package level at it is fine.
