Component with @WebRemote methods can't use @RequestParameter injection
-----------------------------------------------------------------------

                 Key: JBSEAM-1579
                 URL: http://jira.jboss.com/jira/browse/JBSEAM-1579
             Project: JBoss Seam
          Issue Type: Bug
          Components: Core
    Affects Versions: 2.0.0.BETA1
            Reporter: Daniel Young
             Fix For: 2.0.0.CR1


A seam component cannot mix @WebRemote methods with standard methods if the standard methods require @RequestParameter injection.

This worked fine in 1.2.1.GA but is breaking now on 2.0.0 (stacktrace below). Splitting this into two seperate Seam components worked fine.  Possibly the @RequestParameter injection should be skipped when invoking @WebRemote methods.
