NullPointerException on manager.getCurrentAuthProvider()

[GoogleCodeExporter]

I am using 
Socialauth-Spring (4.3) with Spring 3 MVC + Tomcat
by using https://code.google.com/p/socialauth/wiki/SpringSample

AuthProvider provider = manager.getCurrentAuthProvider();
throwing NullPointerException frequently. 

Not sure what I am doing wrong. Any help would be appreciated.

What steps will reproduce the problem?

What is the expected output? What do you see instead?

What version of the product are you using? On what operating system?
Socialauth-Spring 4.3

Please provide any additional information below.

How you are getting manager before calling getCurrentAuthProvider().

Please check the spring example bundled in SDK to get manager object.

Hi Tarun,

Thanks for quick reply! I have followed exactly this code:
http://code.google.com/p/socialauth/source/browse/trunk/socialauthdemo/src/main/
java/com/threepillar/labs/socialauthsample/controller/SuccessController.java

I am getting manager with following statement:

 SocialAuthManager manager = socialAuthTemplate.getSocialAuthManager();

And socialAuthTemplate is injected variable:

@Autowired
private SocialAuthTemplate socialAuthTemplate;

And my servlet.xml file has

 <bean id="socialAuthTemplate"   class="org.brickred.socialauth.spring.bean.SocialAuthTemplate" scope="session">
                <aop:scoped-proxy/>
        </bean>

I saw few threads with similar issues, but they are with JSF framework.

Any other pointers?

Thanks for your time and help.

It seems this issue is related to comment :

from following thread:

http://code.google.com/p/socialauth/wiki/GettingStartedWithYourOwnFramework

Any idea how can I implement this with Spring-SocialAuth?

Thanks for your time and help.

I just want to add few more supporting points, I have created clone of 
SocialAuthWebController.java with few system.out statements.

I have observed that session ids are different when we get control back into 
SuccessController.java. Which may be forcing new instance of SocialAuthTemplate 
with manager as null.

Here is example:

Session id is before authentication...E7557680F892C6776F36691E9DF93CF5
Success controller session ID....     726C2EE5C240BDE4D217CBFDB9C47A0F

Any help or input would be appreciated.
