Lukasz Lenart commented on WW-4775:
-----------------------------------

It is related to a bug in OGNL that was fixed long time ago, see WW-3909 - basically it will work if you generate proper setter/getter, according to the JavaBean  specifications:

{code:java}

private String pName;

public void setpName(String pName) {
    this.pName = pName;
}

public String getpName() {
     return pName;
}
{code}

it is also mentioned in a [migration guide|https://struts.apache.org/docs/struts-23-to-25-migration.html#Struts2.3to2.5migration-Fieldnames]

> Passing request attributes through Ajax - url is not populating the Action Form Attributes and coming up EMPTY . Instead they are available via request object currently. 
> It was working correctly in struts 2.3.16 BUT it is NOT working with Struts 2.5.10 and posing big concern to upgrade to newer version which we want due to security risk.
> To better explain the issue, please check the below snippets. It is big part of our applications code and have a big impacts if we need to move to newer version.
> Below is sniipet of Ajax Method call to Action name:
> {code:javascript}
> function callAjaxGet(value){
> $.ajax( {
> url : "strustSampleActionNameGet",
> type: "GET",
> data : 
> { param : "2"} 
> ,
> success : function(response)
> {alert('success');} 
> ,
> error : function(e)
> {alert('Message on error');} 
> });
> {code}
> ----Action class snippet------
> {code:java}
> public class strustSampleActionClass extends ActionSupport implements SessionAware, ServletRequestAware, ServletResponseAware{
> private String param1;
> //getter and setter exist
> public string getParam1(){
> ...
> }
> public void setParam1(){
> ...
> }
> public String execute() throws exception
> { //getParam1 is null // but we can get it through request String parma1req= getRequest().getParameter("param1"); }
> {code}
