[gatein-dev] Oauth improvement: introduce plug-ability intercept for filling registration-form

Hi all, After implement LinkedIn integration for gatein, i see when i register with LinkedIn, username is being use for registration is illegal and then he must re-input this field, so it's not sense (see attachment) And sometime, user also want to customize the way to prefill oauth registration-form (for example: he want use email for username field) So, we should introduce interceptor plug-ability for handling OAuthPrincipal information before filling to registration form. I created an issue with PR for implementing this at: https://issues.jboss.org/browse/GTNPORTAL-3414 And i also updated at wiki https://community.jboss.org/wiki/OAuthAuthenticationWithSocialNetworks Is there anybody see impact by this change? Thanks!
