[rules-users] Get a value in "when" clause and use it in "then" clasuse

[Wolfgang Laun]

There is no way to do what you want. Evaluation of CEs happens at
one time, and executing the Consequence is done anytime later.

Just call validarNumeroCuenta again in the consequence. If it
is very costly, you might consider implementing a
memoization<http://en.wikipedia.org/wiki/Memoization>
technique.
