    Ajax4JSF configuration issue

    Chintan Parekh Newbie

      Hi,

      We are developing JSF application which uses ajax4jsf. Following version of jars distribution we are using.

      ajax4jsf-1.1.1.jar
      myfaces-api-1.1.5.jar
      myfaces-impl-1.1.5.jar
      tomahawk-1.1.6.jar

      Development environment: JDK 1.4 and Websphere 6.0 app server.

      Problem description:
      when i am using <a4j:support> inside <f:selectItem> it is giving below exception. My managed bean is in "request" scope. but if i put it into "session" scope then ajax call works fine.

      we don't what is real cause of this error. and we can't put all our managed bean into session scope.


      Kindly suggest proper resoultion.
