Why are you using such an old thread that talkes about Abstractchoice?
I see that you use ConverterLocator. and i think thats 1.3. But then you
don't need
to have StringToX and XtoString
Because the converter can do both ways.
And thats also you problem
Because you have to override the same method in StringToUser because
that converter is registered under User.class

Re: convertToString in custom Converter is not called
Posted by narup <ps...@wsgc.com>.
for more details i have a converter
public class UserConverter extends ConverterLocator {
private static final long serialVersionUID = 1L;
public UserConverter () {
super();
set(User.class, new StringToUserConverter());
set(String.class, new UserToStringConverter());
}
}
and also in UserToStringConverter class i have overriden convertToString
method of AbstractConverter but it uses the convertToString from
AbstractConverter class only.
