Hi! The problem is, that Tapestry cannot create an instance of your component LoginLayout.
You probably created a non-default constructor or the constructor is private or protected. Check the Tapestry component lifecycle in case you want to setup your component (for example by using @SetupRender) Best, Thilo ________________________________________ From: squallmat . <squall...@gmail.com> Sent: Thursday, July 03, 2014 11:44 To: users@tapestry.apache.org Subject: java.lang.reflect.InvocationTargetException Hello I have an embedded component into another component but when I try to launch i got this : "Exception assembling root component of page Index: Exception assembling embedded component 'mainlayout' (of type atos.smt.livraison.components.MainLayout, within Index): Exception assembling embedded component 'loginlayout' (of type atos.smt.livraison.components.LoginLayout, within Index:mainlayout): Unable to instantiate instance of transformed class atos.smt.livraison.components.LoginLayout: java.lang.reflect.InvocationTargetException" What the problem could be ? --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
