Balazs Pataki commented on JBSEAM-3965:
---------------------------------------
Maybe it is a different issue, but it seems to be impossible to register a class as both as @Provider and a Seam component (with @Name).
In ResteasyBootstrap there's this warning:
log.warn("not registering as provider Seam component, must be APPLICATION or STATELESS scoped: "
+ seamComponent.getName());
however in ResteasyDispatcher i says:
throw new RuntimeException(
"Registration of STATELESS Seam components as RESTEasy providers not implemented!"
);
This means that at the end only Scope.APPLICATION is allowed. However if I annotate my StringConverter subclass like this:
@Name("MyConverterComponent")
@Scope(ScopeType.APPLICATION)
@Provider
it won't get registered or won't be invoked at all when marshalling the method parameters of my REST calls.

> While using the latest nightly build (from 2009.02.19) I found that my @Provider annotated class is not used by Seam+RESTEasy. It seemed to be loaded but not used by injection mechanism. By debugging the code I found out that it is not used because org.jboss.seam.resteasy.ResteasyDispatcher#onStartup() first registers the resources and after that the providers. However, as part of the resource registration the injection mechanism including the converters are set up, however at this point the converters (providers) have not been loaded.
> It seems to first load the providers and then the resources.
