AjaxFormValidatingBehavior: getting NotSerializableExc
Hello guys,
I'm having a little problem with the use of AjaxFormValidatingBehavior.
I add it to all my fields, using a visitor.
form.visitChildren(FormComponent.class, new IVisitor()
{
public Object component(Component component) {
if (component instanceof TextField) {
component.add(new AjaxFormValidatingBehavior(form,
"onkeyup") {
private static final long serialVersionUID = 1L;
@Override
protected void onError(AjaxRequestTarget
target) {
super.onError(target);
updateFieldsCssClasses();
}
@Override
protected void onSubmit(AjaxRequestTarget
target) {
super.onSubmit(target);
updateFieldsCssClasses();
}
});
} else if (component instanceof DropDownChoice ||
component instanceof CheckBox) {
component.add(new AjaxFormValidatingBehavior(form,
"onclick") {
private static final long serialVersionUID = 1L;
@Override
protected void onError(AjaxRequestTarget
target) {
super.onError(target);
updateFieldsCssClasses();
}
@Override
protected void onSubmit(AjaxRequestTarget
target) {
super.onSubmit(target);
updateFieldsCssClasses();
}
});
}
return null;
}
});
But when this code is rendered, it throws this exception:
org.apache.wicket.util.io.SerializableChecker$WicketNotSerializableException:
Unable to serialize class: xxx$10
Field hierarchy is:
2 [class=xxx, path=2]
...
at java.lang.Thread.run(Unknown Source)
Caused by: java.io.NotSerializableException: xxx.$10
at java.io.ObjectOutputStream.writeObject0(Unknown Source)
at java.io.ObjectOutputStream.defaultWriteFields(Unknown
Source)
However, AjaxFormValidatingBehavior implements Seriablizable... so I
don't understand why Wicket complains about it...
Have I miss something?
PS: it works this way under at least 1.3.0 and 1.3.1

My first guess is that the IVisitor is not serializable. Since you
create two nested anonymous inner classes inside one another, the
behaviors keep a reference to the IVisitor.

That's it! I'm too stupid... sorry for the disturbing ;) Martijn Dashorst a écrit : My first guess is that the IVisitor is not serializable.
