Hi, At "lambdas" [1] branch there are two more features:
1) IReadOnlyModel by Michael Mossman At the moment there are AbstractReadOnlyModel and SupplierModel (extends from AROM). Initially while MM suggested IROM I thought it will be a parent interface of IModel but it is the opposite - IROM extends from IModel. I don't see need of IROM. The classes look enough to me. 2) stream based iteration of container's children by Andrea Del Bene I have said my opinion before - the visitor approach is faster than the stream based one. In addition we have to remove the deprecated org.apache.wicket.util.iterator.AbstractHierarchyIterator and its related classes because it fails with StackoverflowError when used in a page with bigger component tree. So I don't see a reason for this feature. Your option on them ? 1. https://github.com/apache/wicket/compare/lambdas Martin Grigorov Wicket Training and Consulting https://twitter.com/mtgrigorov
