javax.faces.FacesException: javax.el.PropertyNotFoundException
Hi All,
I have created one seam component namely testTableManager and its both stateful and session scoped. (does stateful bean need to be session scoped?).Here, this component some properties which i want to access from the xhtml page but i am getting following error:
javax.faces.FacesException: javax.faces.FacesException: javax.el.PropertyNotFoundException: /test/testTable.xhtml @74,105 colspan="#{sessionScope.testTableManager.conditionFields}": Property 'conditionFields' not found on type org.javassist.tmp.java.lang.Object_$$_javassist_8

Please, help me to resolve this PropertyNotFoundException.
Also tell me if i want to use following code for storing the session, will it work?
Code nto seam component which is of Event or Conversation scope:
/*javax.servlet.http.HttpSession session=(HttpSession)facesContext.getContext().getExternalContext().getSession(true);
session.setAttribute("conditionFileds", "4");
session.setAttribute("Name","Test");*/
Code to access Session attributes from the .xhtml page:
<h:outputText value="#{sessionScope.Name}" size="6" />
Its urgent to get this PropertyNotFoundException to be solved so help me out.
Thanks a lot in advance.
Regards,
Manish

Please, help me to resolve this PropertyNotFoundException.
Also tell me if i want to use following code for storing the session, will it work?
Code nto seam component which is of Event or Conversation scope:
/*javax.servlet.http.HttpSession session=(HttpSession)facesContext.getContext().getExternalContext().getSession(true);
session.setAttribute("conditionFileds", "4");
session.setAttribute("Name","Test");*/
Code to access Session attributes from the .xhtml page:
<h:outputText value="#{sessionScope.Name}" size="6" />
Its urgent to get this PropertyNotFoundException to be solved so help me out.
Thanks a lot in advance.
Regards,
Manish
