Numeric Limit Test is not assigning variables in post expression (TS2010 SP1)

Hello all,

I have faced very strange problem using Step properties of "Numeric Limit Test" in post expressions:

I have several variables which stores values for DataSource and Limits of "Numeric Limit Test" step. I'd like to assign these variable values to another variables in the post expression. 

The problem is I can not get the values in the post expression, I don't understand why. If I use another step and "PreviousStep" I can assing them properly but I would like to do it in the post expression instead.

Also I have try to disable the "Optimize non-reentrant calls...". If I disable It, I have "0" value in my variables, if I enable it, I have the value of last execution.

You will see very easy in the attached small sequence as example of this issue.

Someone has idea of what and why is this happening?

Many thanks,

Hector.
