Using WSO2 and OwnUserStore and an own claim - wso2

Question

I am using WSO2 4.6.0 with an own UserStoreManager. That basically works (mostly) unless I want to read or write an attribute to a user profile. I want to add an additional attribute called token. I created a claim named
http://wso2.org/claims/token
But, after I added this claim to my SAML provider, I can't login anymore with the following exception:
[2014-06-10 00:24:22,635] ERROR {org.wso2.carbon.identity.sso.saml.builders.ResponseBuilder} - Error when reading claim values for generating SAML Response

I get the same exception (without the SAML Response part) when trying to edit my user profile. Apparently I have to do something to force the WSO2 to call methods of my UserStore in order to edit a profile, but I can't find out what yet.
Any hints?
regards
Leon

Answer 1

I think this is an issue with the user store manager that you have written. As this is a null pointer exception, you can go through the 778 line in the AbstractUserStoreManager and find out, why null has been generated. I guess, This is due to that, in your custom user store manager, you are not initializing the claimManager. Please verify the constructors of your custom class. You can find the source code of user core from here
