Only if you consider less the same as cleaner. If you are doing a lot of inter-component interactions, this would actually be a disadvantage. What I (and collegues) do a lot is use a component (e.g. a panel) and a bunch of nested classes in that panel (Panels, fragments, other) that uses state and methods of the outer component. For situations where the UI is complex, it saves a lot of effort to work like this, and imo you end up with very nice encapsulated components with minimal plumbing. Imo, being able to work like this is one of the biggest pro's compared to declaratively composing your component tree. > - Components are declared in HTML, configured in another file, binding > (configuring) the component with the java class.

That's a very good point for WO, which can be used to > build > public stateless websites. 1.2.x has a limited availability of stateless pages: pages are stateless when there are no callbacks to itself (like links or forms). If you would do everything using bookmarkable pages, your app would be stateless (though for 1.2.x, an http session object would still be created). In 2.0 we are working at dramatically increase the options you have for working in a stateless fashion. We have deferred session creation (http session is now only created when really needed/ first time a stateful page is served or session state is explicitly saves) and more options to use stateless pages, like StatelessLink and StatelessForm. This is implemented now (please play with it) and should already cover enough to create serious stateless applications. I think this feature is very useful for situations where you have an anonymous, public facing part of a site which should be stateless and other parts where the UI gets so complex you really need the stateful model. > - Wicket has nice URLs (if we want to).

Can you expand on where/ why you think that difference comes from? Are some of the default components of WO better abstracted for the kind of things you do? > - Both frameworks make creation of custom components easy (unlike JSF!!!) > > - Wicket custom components can be shared with a simple jar, WO components are > bundled in "Frameworks" (custom packages). > > - Both frameworks are not using XML for configuration...
