GroovyScript teststeps not working in Pro version

Hi,

I created a project in an old free version of soapUI and used this GroovyScript to generate new users:

int random =  ((int)(Math.random()*99999))
context.setProperty( "PropName", "prefix" + random )

This works in the old version, but not in soapUI Pro 5.0.0.

Any ideas?
