Wow. Which version are you using? Can you give an example of the code
produced by myFunctionCode.toString()? How do you create your scope object?
FYI, the test below prints 4 on stderr.
public class TestLength {
public static void main(String[] args) {
Context.call(new ContextAction() {
public Object run(Context cx) {
cx.setOptimizationLevel(9);
ScriptableObject scope =
cx.initStandardObjects();
Function function = cx.compileFunction(scope,
"function(a, b, c,
d){}", "-", 1, null);
System.err.println(ScriptRuntime.getObjectProp(function, "length", cx));
return null;
}
});
}
}
Could you run it?
