Getting Error "Field not serializable" on one of the constructor
attrib ?
Guys,
Not sure why, but wicket is giving me an error "Field that is not
serializable" on one of constructor attributes (of a panel) which is an
implementation to an interface...i wonder why is that ? The attribute is not
used as a model or anything its just a serviceHandler which i am passing to
the page-component.
Error log
----
private final org.xyz.login.api.I_LoginService
org.xyz.login.web.LoginPane

Apache Wicket 1.3.0-rc1 is released

Re: Getting Error "Field not serializable" on one of the constructor attrib ?
Posted by Igor Vaynberg <ig...@gmail.com>.
class DependencyProvider<T> implements Provider<T>, Serializable {
private String typeName;
public final DependencyProvider(Class dependencyType) {
typeName=dependencyType.getName();
}
public T get() {
return ((MyApplication)Application.get()).getDependency(Class.forName(typeName));
}
}
then you can do
final Provider provider=new DependencyProvider(Dao.class);
new Form("foo") { onsubmit() { provider.get().foo(bar); }}
notice that the dependencylocator instance can be serialized without
serializing the dependency iitself... thats the important part.

yes it should. this is how anonymous classes work.

the work around is to pass in a locator that can be serialized without
serializing the dependency yet knows how to look it up when it is
needed. kinda like a serializable lookup. this is what wicket's
@SpringBean proxies do. the other option is to have that service
available via a static lookup.

Re: Getting Error "Field not serializable" on one of the
constructor attrib ?
Posted by mfs <fa...@gmail.com>.
hmm..but should it do that?...its not an instance within the form, i mean
we'll be invoking the service layer from within the form.onsubmit (most of
the times) event, and that would require all the service or other classes
invoked to be made serializable..
Whats the work around, i wouldnt want the service class (or perhaps any
other class) be made serializable without a reason..
Thanks in advance

Re: Getting Error "Field not serializable" on one of the
constructor attrib ?
Posted by mfs <fa...@gmail.com>.
Ok...so here is the LoginPanel class...with the constructor i was referring
to .. further the implementation for I_LoginService (i.e. LoginService...on
which the serializable error is pointing to) is being passed over from the
caller component...
public class LoginPanel extends Panel {
LoginVO loginVO = null;
public LoginPanel(String id, final String targetPage, final I_LoginService
loginServiceHandler) {
super(id);
loginVO = new LoginVO();
setModel(new CompoundPropertyModel(loginVO));
Form loginForm = new Form("loginForm") {
protected void onSubmit() {
loginServiceHandler.authenticate(loginVO.getUserName(),
loginVO.getPassword());
}
};
loginForm.add(new RequiredTextField("userName"));
loginForm.add(new PasswordTextField("password"));
Button loginButton = new Button("loginButton") {
public void onSubmit() {
}
};
loginForm.add(loginButton);
add(loginForm);
}
