[rules-users] Declaring Variables in Condition

[Edson Tirelli]

    Markus,

    It may be a problem with the $ symbol that has special meaning in
regexps. Although, if that is the case, it is a bug in the DSL mapping
engine.
    Can you confirm that not using it resolves your problem? What shows up
in the DRL viewer when you open a DSLR file using your grammar?
