Am I correct > about this? Basically yes. Any non-transient field in your Component will be serialized. That includes final local variables or final method/constructor parameters if you reference those from within an inner class. That will make the compiler generate a hidden field to keep that reference for the inner class.

Wicket serialization concerns
I could use some input from some of the more experienced Wicket users out there. I'm having a hard time fully understanding when to worry about Wicket attempting to serialize domain model objects, resulting in serialization warnings/errors in the logs. I had been under the impression that if I had an object as a field in a Wicket component, I needed to be on alert for serialization issues. So, if I have an object as a field, I make it a LoadableDetachableModel. In cases where I need to load in a wired object, I make use of the handy @SpringBean annotation. Otherwise, I assumed I was in the clear but I'm seeing now that's not the case. In a method within a webpage component, I'm creating a List collection of domain objects for use in a form's DropDownChoice component. Unless I put that list in a LoadableDetachableModel, I will get a serialization error. I'm led to believe that creating a reference to any of my domain classes within a Wicket component (as a field or in a method implementation) will expose me to a serialization error unless I put it in a Wicket model. Am I correct about this? Thanks! Mike Chandler
Re: problem header contribution with ajax
Martin Grigorov schreef: Hi Martin, Thanks for your quick answer. You cannot replace header contributions with the same HTML id attribute. Wicket checks whether the contribution is already in the page and ignores it. Ok, that explains a lot. You can use normal Label component to be able to replace it in Ajax responses. I am not fully understanding this, could you give more detail about the suggested solution? thanks, Haiko - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

problem header contribution with ajax
Dear wicket-users, I notice that a header contribution by a panel is not rendered in the following case. An inline CSS in the head section is first rendered by switching tabs when i rerender the panel with a slighty different header contribution, then panel is rerendered but the header contribution is not picked up. id="style.widget.titel" > Has anyone ideas how to debug this? Is it not possible to replace a header contribution with the same ID? thanks in advance, Haiko - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: Wicket security and JavaMelody
I ended having to write a custom JDBC Realm since i have used a salt for
users passwords.
import org.apache.catalina.realm.JDBCRealm;
import org.apache.juli.logging.Log;
import org.apache.juli.logging.LogFactory;
import
org.springframework.security.authentication.encoding.ShaPasswordEncoder;
import java.security.Principal;
/**
* @author
*/
public class EazyregnskabRealm extends JDBCRealm {
private static final Log log =
LogFactory.getLog(EazyregnskabRealm.class);
ShaPasswordEncoder encoder = new ShaPasswordEncoder(256);
@Override
protected String getName() {
return this.getClass().getSimpleName();
}
@Override
public synchronized Principal authenticate(String username, String
credentials) {
String unDigestedPassword = credentials;
String digestedPassword =
encoder.encodePassword(unDigestedPassword, username);
return super.authenticate(username, digestedPassword);
}
}
web.xml
BASIC
Monitoring
USER
MONITOR
Monitoring
/monitoring
MONITOR
server.xml
The EazyregnskabRealm.class must be made into a jar, this and all other
dependencies should be put in the tomcat lib folder. Hope someone else can
use this.
