Hello everyone, I'm doing some new code and trying rhino.  I want to
build up a class object by evaluating strings but it doesnt seem to
work the way I expect.  here is the relavent code, that doesnt seem to
work.  it's pretty straightforward...


-----------------------------------------------------------------

  Context context = Context.enter();
  Scriptable scope = context.initStandardObjects();

  evaluateString("function CLASS() {}");
  evaluateString("CLASS.x = 5");

  //
  // everything up to here is fine, but the next line fails:
  //
  evaluateString("CLASS.blah = function() {}");

-----------------------------------------------------------------

(for clarity evaluateString() is defined as:

-----------------------------------------------------------------
    public void evaluateString(String code) {
      context.evaluateString(scope, code, "<cmd>", 1, null);
    }
-----------------------------------------------------------------

the first block fails with the following exception at the last line...

    Exception in thread "main" java.lang.VerifyError: (class:
    org/mozilla/javascript/gen/c3, method: _c0 signature:
    (Lorg/mozilla/javascript/gen/c3;Lorg/mozilla/javascript/Context;
    Lorg/mozilla/javascript/Scriptable;Lorg/mozilla/javascript/Scriptable;
    [Ljava/lang/Object;)Ljava/lang/Object;) Incompatible argument


anyone willing to hand me a small clue, would be greatly
appreciated...
