StackOverflowError when calling user.save()
Hello!
I'm setting up a turbine/torque site and I am having trouble with my user om
class. Calling the save method initiates a circular pattern of method calls.
After a few seconds the JVM thorws a StackOverflowError. At first I thought
it might have something to do with my configuration on extending the turbine
user but I tried to do it with the turbine user class
(org.apache.turbine.om.security.TurbineUser) and the same error occurs.
Here is my code:
TurbineUser user = new TurbineUser();
user.setEmail("r2@d2.com");
user.setName("R2D2");
user.setPassword("ilovec3po");
user.setFirstName("R2");
user.setLastName("D2");
user.save();
This is the stack trace that is printed:

The four last lines then loop forever (at least for a long while =) )
I took a look in the code for TorqueUserManager and the last thing done in
the createAccount-method is to save the user object wich does indeed start
the process over again. Is this correct?
Any help is appreciated.

RE: StackOverflowError when calling user.save()
Posted by Ludwig Magnusson <lu...@greenstreetconsulting.se>.
Thank you, it is a little bit clearer now.
One thing I don't understand however is this:
In
http://turbine.apache.org/turbine/turbine-2.3.3/services/torque-security-ser
vice.html there is an exapmple of an extended user class. It looks lie this:
public class ExtendedUser extends TorqueUser
{
public ExtendedUser()
{
super();
}
public ExtendedUser(Persistent obj)
{
super(obj);
}
public String getPhone()
{....
How is this class created? Do I write it myself or is it created via the ant
script? The thing that confuses me is that it extends TorqueUser and not
BaseExtendedUser. How do I make that connection?

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

It will make everything a lot clearer

AW: StackOverflowError when calling user.save()
Posted by Juergen Hoffmann <ho...@apache.org>.
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
