Hi,
The new way is to use the dynamic extra parameters.
Each Ajax behavior and component has a method
#updateAjaxAttributes(AjaxRequestAttributes attributes) :
attributes.getDynamicExtraParameters().add("return [obj1, obj2, ...]").
Where objN are JavaScript objects like: {"name":
formComponent.getInputName(), "value":
Wicket.Form.serialize(Wicket.$('"+formComponent.getMarkupId()+"')) }
The above is a pseudo code but I hope you follow me.
