GIVEN RULE:

rule "Nested nested model rule - doesn't compile"
    dialect "mvel"
when
    $model : Model( $nestedModel : nestedModel,
                    $nestedNestedModel : nestedModel!.nestedNestedModel,
                    "NestedNestedModelName".equalsIgnoreCase(nestedModel!.nestedNestedModel!.nestedNestedModelName) )
then
    System.out.println( "I'm a  nested nested model! My name is [" + $nestedNestedModel.nestedNestedModelName +"] " );
end

The following error occurs:
