Java – signoutForm on stateless page

javawicket

i have a web site which is created by wicket(java) but in special cases i got following error.

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()
