AW: StackOverflowError when calling user.save()

Hi Ludwig,

so not use the TurbineUser Directly. Please use TurbineSecurity Object for
that.

Please read 

http://turbine.apache.org/turbine/turbine-2.3.3/apidocs/org/apache/turbine/s
ervices/security/TurbineSecurity.html
http://turbine.apache.org/turbine/turbine-2.3.3/services/torque-security-ser
vice.html

It will make everything a lot clearer

Kind regards

Juergen
