      Use JBossInjectionProvider by adding the following to web.xml

      <context-param>
      <param-name>com.sun.faces.injectionProvider</param-name>
      <param-value>org.jboss.web.jsf.integration.injection.JBossInjectionProvider</param-value>
      </context-param>

      Or, do not overload the method.

      If there was a @PostConstruct annotation, or other annotation, on a method which was overloaded by another method with the same name, the call to that method would fail with an exception error. This occurred because no arguments were passed to the method and only the presence or absence of the method was being checked, not the presence or absence of methods. To resolve this issue further checks have been added so that the presence of parameters is confirmed prior to the method being invoked.

    Description

      When overloading a method with two implementations, like so:

      @PostConstruct
      public void init()

      { this.name = "init () no args"; }

      public String init(Object foo)

      { this.name = "init () with foo"; return null; }

      PostConstruct invocation fails with an error:

      2011-08-29 16:41:17,434 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/jsfHello].[jsp]] (http-localhost%2F127.0.0.1-808
