    Caught RuntimeException "JNDIProjectStageDetector didn't implement the Extension interface"

    paul_

      Hi,

       

      i am currently migrating an application from jsf1.2 (richfaces 3.3) to jsf2.0 (richfaces 4) (from JBoss 4.2 to JBoss 7 and Seam 2 to Seam 3)

       

      I almost got it working now, finished replacing the jar files and resolving the dependencies. When starting the application i get a RuntimeException:

       

      "java.lang.RuntimeException: Service class org.jboss.seam.faces.projectstage.JNDIProjectStageDetector didn't implement the Extension interface"

       

      I set the ProjectStage in my web.xml:

       

          <param-name>javax.faces.PROJECT_STAGE</param-name>
          <param-value>Development</param-value>

       

      Do I have to implement a class for this to work?

      Couldn't find anything on the web or here in the community for this specific error...
