Sorry, was busy at work last week. Please find attached sources and jar with compiled classes.
Usage is extremely simple: add ru.pronto.wicketextras.StatelessChecker to postComponentOnBeforeRenderListener list and add @StatelessComponent to any components you want to guarantee be stateless. If any of them will become statefull (either directly or because of any child) then exception will be thrown with explanation what component is to blame. 2009/3/13 Alex Objelean <alexandru.objel...@isdc.ro>: > > Marat, as you can see people are interested.... and waiting for this feature > to be published somewhere > > Alex > > > Marat Radchenko-2 wrote: >> >> Wicket pages/components can be either stateful or stateless.
