> NPE when deploying an app with Seam Faces
> -----------------------------------------
>
> Key: SEAMFACES-18
> URL: https://jira.jboss.org/browse/SEAMFACES-18
> Project: Seam Faces
> Issue Type: Bug
> Components: JSF CDI Integration
> Affects Versions: 3.0.0.Alpha2
> Environment: Glassfish v3 on Fedora 12 with Sun Java 1.6 u20
> Reporter: Brian Leathem
>
> I've developed an app using custom @ViewScoped and @FlashScoped annotations (see: http://github.com/verborghs/jsf-cdi). I swapped out the custom scope implementations with ones from the Seam3 project (changing the import statements accordingly). On deploying the app, I get the NPE below.
> I'll work on creating a small test project to reproduce this error.
