Re: Reload button causes wierd behavior

That's because throwing PageRedirectException simply calls cycle.activate(...). To perform a true redirect (so that the page can be reloaded without re-executing your listener method), do the following:

IEngineService service = cycle.getEngine().getService(Tapestry.PAGE_SERVICE);
ILink link = service.getLink(cycle, cycle.getPage(), new String[] { "PageB" });
throw new RedirectException(link.getURL());

class PageA {

            PageB page = (PageB) cycle.getPage("PageB");
            throw new PageRedirectException(page);
 }
 }
