Entity and transactions

[Lukas Stephienn]

suppose we have entity (EJB 2.0):

//...
public abstract void setFirstName(String firstName);
public abstract String getFirstName();
 
public abstract void setLastName(String lastName);
public abstract String getLastName();
 
punlic String getFullName() {
  return getFirstName() + " " + getLastName();
}
//...

and suppose, all of these methods are defined in EJBObject interface;

Can we be sure that getFullName() will be executed only in one transaction?
Does always container calls ejbStore() after this method? Even if I did not invoke any setter? Maybe it depends on the container...
