No, there is nothing about this in Wicket 7.x.
I don't think there will be something in 8.x too. We are not big fans of
auto-magical functionalities.
We prefer to give you the facilities (like the factory methods, visitors,
etc.) and let you define your application logic.
What I'd do for your use case is to extend OnChangeAjaxBehavior, override
its #updateRequestAttributes() with attributes.setChildSelector("input,
select, textarea") and attributes.getDynamicExtraParameters("return
collectChildrenFormElementsValues(attrs.c)") and then in onChange() read
the submitted values and update the form components.
But you will need Wicket 6.x for all this...
