Thank you Olaf and Michael. I think this is workable... We can create an abstract base class that instead of doing load() directly, the signature would be something like:
public Future<T> load(ExecutorService executor); The async load() will execute immediately upon model creation, and during the "actual" LoadableDetachableModel.load(), it will simply wait for the future to complete (if it hasn't completed). Since there can be multiple futures executing at one time, no model is blocked by the loading of another model. That's in theory... Hopefully it will actually work as intended. :) Is there a plan to make this asynchronous model support built-in in Wicket? With asynchronous frameworks like Play and vert.x, I think Wicket needs to improve on this front too to keep itself relevant. If anyone else also have a need for this (at least there are 3 of us) I can file a ticket.
