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.
