我有一个由wicket（java）创建的网站，但在特殊情况下我遇到了以下错误。
WicketMessage: unable to find component with path signoutForm on stateless page [Page class = ir.pnusn.ui.Dispatcher, id = 1, version = 0] it could be that the component is inside a repeater make your component return false in getStatelessHint()
Root cause:
org.apache.wicket.WicketRuntimeException: unable to find component with path signoutForm on stateless page [Page class = ir.pnusn.ui.Dispatcher, id = 1, version = 0] it could be that the component is inside a repeater make your component return false in getStatelessHint()
