resolver problem

Hello,

With the folowing expression:

	getIntegerProperty("repHdrLen")-2

- When setting no resolver: compiles and evaluates
with no pb.

- When setting a resolver I get the following
Exception when compiling:

	gnu.jel.CompilationException: Dynamic variable cant
have the formal parameters.

I don't understand why setting a resolver changes the
behaviour with this expression.
Can someone explain this?

- keeping the resolver and setting the expression to:

	repHdrLen-2

I get the following Excetpion:
