JSPX requestScope/sessionScope/applicationScope Error

Question

Dear Jdeveloper Experts,
I am currently using JDeveloper 10.1.3.3.0.4157, and new to Oracle ADF. I did some research in OTN and know that the following error come from Oracle pragma thing ? I appreciate your help to resolve the following error:
My backing view class :
public class MissionSearch {
(getter and setter default codes of ADF Core components ....)
My backing view class defined in faces_config.xml:
<managed-bean>
<managed-bean-name>backing_app_Common_MissionSearch</managed-bean-name>
<managed-bean-class>tomis2.menus.navigation.view.backing.app.Common.MissionSearch</managed-bean-class>
<managed-bean-scope>request</managed-bean-scope>
<!--oracle-jdev-comment:managed-bean-jsp-link:1app/Common/MissionSearch.jspx-->
</managed-bean>
and so on..........
My jspx page ADF Faces example:
#{binding.argMctry.inputValue} from Data Control (table search using parameters)
<af:selectInputText value="#{bindings.argMctry.inputValue}"
label="Country/Org"
columns="30"
binding="#{backing_app_Common_MissionSearch.ctryIn}"
id="ctryIn" windowHeight="600"
windowWidth="350"
returnListener="# {backing_app_Common_MissionSearch.handleCtry}"
action="dialog:openMCtry"/>
and so on......
When testing page using OC4J (local) I encountered the following error:
500 Internal Server Error
javax.faces.el.PropertyNotFoundException: Error testing property 'inputValue' in bean of type null at com.sun.faces.el.PropertyResolverImpl.isReadOnly(PropertyResolverImpl.java:274) at oracle.adfinternal.view.faces.model.FacesPropertyResolver.isReadOnly(FacesPropertyResolver.java:124) at com.sun.faces.el.impl.ArraySuffix.isReadOnly(ArraySuffix.java:236)
and so on..........
Thank you very much for your help.

You have to check out your page definition. Either the attribute you are referencing does not exist in the page definition or there nay exist a miss-spelling. If this is your only VO attribute. If there exist more, you have to check them all, since the problem may originate from another attribute.
