Sachin Tandon commented on WW-3415:
-----------------------------------
Yes, I have come up with a work around.
I have changed the handleInvalidToken method as follows:- Changes made are
starts with the comment "//Changes start" and ends with "//Changes end"
protected String handleInvalidToken(ActionInvocation invocation) throws
Exception {
ActionContext ac = invocation.getInvocationContext();
HttpServletRequest request = (HttpServletRequest)
ac.get(ServletActionContext.HTTP_REQUEST);
HttpServletResponse response = (HttpServletResponse)
ac.get(ServletActionContext.HTTP_RESPONSE);
String tokenName = TokenHelper.getTokenName();
String token = TokenHelper.getToken(tokenName);
if ((tokenName != null) && (token != null)) {
Map params = ac.getParameters();
params.remove(tokenName);
params.remove(TokenHelper.TOKEN_NAME_FIELD);
ActionInvocation savedInvocation =
InvocationSessionStore.loadInvocation(tokenName, token);
if (savedInvocation != null) {
// set the valuestack to the request scope
ValueStack stack = savedInvocation.getStack();
Map context = stack.getContext();
request.setAttribute(ServletActionContext.STRUTS_VALUESTACK_KEY, stack);
ActionContext savedContext =
savedInvocation.getInvocationContext();
savedContext.getContextMap().put(ServletActionContext.HTTP_REQUEST, request);
savedContext.getContextMap().put(ServletActionContext.HTTP_RESPONSE, response);
Result result = savedInvocation.getResult();
if ((result != null) &&
(savedInvocation.getProxy().getExecuteResult())) {
synchronized (context) {
result.execute(savedInvocation);
}
}
// turn off execution of this invocations result
invocation.getProxy().setExecuteResult(false);
//Changes start
//Checks if the saved invocation has been executed as of now.
If not it gets executed again.
if(savedInvocation.isExecuted()){
return savedInvocation.getResultCode();
}else{
return savedInvocation.invoke();
}
//Changes end
}
}

> Issues with Token session interceptor - Blank page is returned in case of

> Key: WW-3415
> URL: https://issues.apache.org/jira/browse/WW-3415
> Project: Struts 2
> Issue Type: Bug
> Components: Core Interceptors
> Affects Versions: 2.0.11.1
> Reporter: Sachin Tandon
>
> Blank page is returned in case of double submission. I am using struts
> version - 2.0.11.1
> I have extendend TokenSessionStoreInterceptor class in my code and not
> changed any functionality. Following is how my class looks like
> public class MyClass extends TokenSessionStoreInterceptor{
> /**
> * Default Serial Version Id
> */
> private static final long serialVersionUID = 1L;
>
> protected String handleInvalidToken(ActionInvocation invocation) throws
> Exception {
> ActionContext ac = invocation.getInvocationContext();
> HttpServletRequest request = (HttpServletRequest)
> ac.get(ServletActionContext.HTTP_REQUEST);
> HttpServletResponse response = (HttpServletResponse)
> ac.get(ServletActionContext.HTTP_RESPONSE);
> String tokenName = TokenHelper.getTokenName();
> String token = TokenHelper.getToken(tokenName);
> if ((tokenName != null) && (token != null)) {
> Map params = ac.getParameters();
> params.remove(tokenName);
> params.remove(TokenHelper.TOKEN_NAME_FIELD);
> ActionInvocation savedInvocation =
> InvocationSessionStore.loadInvocation(tokenName, token);
> if (savedInvocation != null) {
> // set the valuestack to the request scope
> ValueStack stack = savedInvocation.getStack();
> Map context = stack.getContext();
>
> request.setAttribute(ServletActionContext.STRUTS_VALUESTACK_KEY, stack);
> ActionContext savedContext =
> savedInvocation.getInvocationContext();
>
> savedContext.getContextMap().put(ServletActionContext.HTTP_REQUEST, request);
>
> savedContext.getContextMap().put(ServletActionContext.HTTP_RESPONSE,
> response);
> Result result = savedInvocation.getResult();
> if ((result != null) &&
> (savedInvocation.getProxy().getExecuteResult())) {
> synchronized (context) {
> result.execute(savedInvocation);
> }
> }
> // turn off execution of this invocations result
> invocation.getProxy().setExecuteResult(false);
> return savedInvocation.getResultCode();
> }
> }
> return INVALID_TOKEN_CODE;
> }
> protected String handleValidToken(ActionInvocation invocation) throws
> Exception {
> // we know the token name and token must be there
> String key = TokenHelper.getTokenName();
> String token = TokenHelper.getToken(key);
> InvocationSessionStore.storeInvocation(key, token, invocation);
>
> return invocation.invoke();
> }
> }
> Now, whenever I do a double submission for a functionality like search (which
> gets loads of data from the database), previously saved invocation does not
> complete and savedInvocation.getResultCode() returns null (inside
> handleInvalidToken method). Due to which I receive a blank page.
> Whenever I do a debug(from eclipse) on handleInvalidToken method,
> savedInvocation.getResultCode() value changes from null to "success" as I
> wait inside the method for sometime.
> I have also put in savedInvocation.isExecuted() in this handleInvalidToken
> method and noticed that its value changes from false to true if I wait on the
> line of code for some time.
