AjaxFormSubmitBehavior causes serialization issues inside
onBeforeRender()
Hi fellow wicket users,
I am a user of Wicket 1.4.8
I am trying to use a TabbedPanel inside which there are several individual
Panels. Now one of the Panel has a form with quite a few RadioChoices and
DropDownChoice objects. I am updating a top level flag whenevr there is any
change on any form element to trigger a pop-up asking the user to save
un-saved changes on the page when they try to move away from that tabbed
panel to soem other page.
Since there are multiple form elements I am using a onBeforeRender() method
in the ChildPanel class and applying AjaxFormBehaviour on all child elements
at one place to avoid redundancy of code for each radio element or dropdown
element as follows -
protected void onBeforeRender() {
if (!behaviorAssigned) {
behaviorAssigned = true;
visitChildren(new IVisitor<Component>() {
public Object component(Component component) {
if (component instanceof RadioChoice) {
component.add(new AjaxFormSubmitBehavior("onclick") {
@Override
protected void onError(AjaxRequestTarget target) {
// TODO Auto-generated method stub
}
@Override
protected void onSubmit(AjaxRequestTarget target) {
parent.setPageChanged(Boolean.TRUE);
}
});
}
if (component instanceof DropDownChoice<?>) {
component.add(new AjaxFormComponentUpdatingBehavior(
"onchange") {
protected void onUpdate(AjaxRequestTarget target) {
parent.setPageChanged(Boolean.TRUE);
}
});
}
return null;
}
});
super.onBeforeRender();
}
Problem is whenever the Panel is loaded I am getting loads of
WicketNotSerializableExceptions -
org.apache.wicket.util.io.SerializableChecker$WicketNotSerializableException:

However when I add the AjaxFormSubmitBehaviour to individual form components
and comment out the onBeforeRender it works fine without any errors..
any clue guys?

Re: AjaxFormSubmitBehavior causes serialization issues inside
onBeforeRender()
Posted by allgo <so...@yahoo.co.in>.
Thanks a lot Igor. That explains it all.
I was able to fix it today by using
visitChildren(ChildPanel.class, new IVisitor<Component>())
instead of
visitChildren( new IVisitor<Component>())
I guess, else it tries to add teh behaviour to all objects up the hierarchy
instead of restricting itself to only the ones on ChildPanel.class
Thanks,
Allgo

Re: AjaxFormSubmitBehavior causes serialization issues inside onBeforeRender()
Posted by Igor Vaynberg <ig...@gmail.com>.
because your behavior is an anonymous class it keeps a reference to
its parent - the visitor. visitors are not serializable. the easiest
way to fix it is to make the behavior you are adding an inner class of
the page.
