The c in CBookingFactorsBean should be lower case , I think.

Subject: RE: Struts2 - OGNL - access bean property in model object
Hi Rouxel,
I am using ScopedModelDriven.
I am not using prepare,since ModelDSriven interceptor takes care of
initializing model object.
I have following implemented methods of ScopedModelDriven and other servlet
config related methods in my Action class.
--------------------
public Object getModel(){
System.out.println("getting model.");
return cBookingFactorsModel;
}
public String getScopeKey() {
System.out.println("getting key.");
return key;
}
public void setModel(Object obj) {
System.out.println("setting model: "+obj.toString());
this.cBookingFactorsModel=(CBookingFactorsModel)obj;
}
public void setScopeKey(String key) {
System.out.println("setting key: "+key);
this.key=key;
}
public void setServletRequest(HttpServletRequest request) {
this.request=request;
}
public void setSession(Map map) {
this.session_map=map;
}
public CBookingFactorsModel getCBookingFactorsModel() {
return cBookingFactorsModel;
}
public void setCBookingFactorsModel(CBookingFactorsModel
bookingFactorsModel) {
cBookingFactorsModel = bookingFactorsModel;
}
