Hi Chris,
I am able to resolve the issue by initializing the Bean object in Model when
page loads.
Action class
//-- baen initialize --//
this.cBookingFactorsModel.setCBookingFactorsBean(new CBookingFactorsBean());
JSP Page:
<s:textfield name="cBookingFactorsBean.salesAfterDiscount" size="13"
cssClass="Input"/>
But the error on server console is still seen.
WARNING: Error setting value
ognl.OgnlException: target is null for setProperty(null,
"salesAfterDiscount", [Ljava.lang.String;@e6235d)
at ognl.OgnlRuntime.setProperty(OgnlRuntime.java:1651)
Any idea

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;
}
