------------------------------------------------------------------

after creating the quick start app, I noticed that you have to set  the 
RenderStrategy.REDIRECT_TO_RENDER in your 
org.apache.wicket.WicketApplication.init() to make the bug occur.

you will find the file attached.

thank you too!

> we have a page with
> - a login form A (org.apache.wicket.markup.html.form.StatelessForm<T>)
> - a standard form B inside a panel which is secured with 
> @AuthorizeAction(action = Action.RENDER...)
> our problem: the user must submit the login form twice.
> reason:
> - when the page is requested the first time, the page is stateless cause none 
> of the visible children are stateful.
> - when the user now submits the login form, the page claims to be stateful, 
> the stateful component is form B. 
> - 
> org.apache.wicket.core.request.handler.ListenerInterfaceRequestHandler.respond(IRequestCycle)
>  now handles the page as expired and omits the submit
> possible buggy code: 
> - the visiblity of components is computed before rendering in 
> org.apache.wicket.Component.setRenderAllowed()
> - 
> org.apache.wicket.core.request.handler.ListenerInterfaceRequestHandler.respond(IRequestCycle)
>  calls only org.apache.wicket.MarkupContainer.internalInitialize() on the 
> current page to give it a chance for computing its visibility, 
> Component.setRenderAllowed() is not called
