DeadBolt 2 NullPoniterException error in playframework 2 app

Question

I am developing a web app and I am using the way zentasks sample app uses for user authentication so after login is done, username is stored in session. Now I am trying to do the authorization part with DeadBolt 2 plugin. Basically I have merged the sample DeadBolt 2 app into my own application. The only difference is that I am using 2.sql to bootstrap the default data instead of Global.java(and with different role names than foo & bar). Now after login when I try to access a controller method annotated by @SubjectPresent, I get NullPointerException with the following stacktrace:

[error] play - Cannot invoke the action, eventually got an error: java.lang.NullPointerException
[error] application -

Any ideas on where it has gone wrong?

EDIT: I switched to RC4 and this time I got this error using @Restrict

2.2-RC1 still working pretty fine and I've had no problem with it using play 2.2.0.

Answer 1

I've fixed this and released a new version - switch to version 2.2-RC4 and you should be fine.

"be.objectify" %% "deadbolt-java" % "2.2-RC4"
