Esta muestra 3 de los siguientes mensajes de advertencia :

Advertencia: esta página requiere espacio de nombres XML declarado con entrada de prefijo, pero no existe taglibrary para ese espacio de nombres.

Cuando quito la etiqueta <p:panel>, entonces no aparecen esos mensajes. ¿Cómo es esto causado y cómo puedo resolverlo?

Answer 1

Has declarado elementos simples de HTML <input> y el analizador XML de alguna manera no se ha configurado para usar http://www.w3.org/1999/xhtml como espacio de nombres XML global. Agregalo usted mismo.
