> @Providers not working - ResteasyDispatcher registers components and providers in wrong order

> Key: JBSEAM-3965
> URL: https://jira.jboss.org/jira/browse/JBSEAM-3965
> Project: Seam
> Issue Type: Bug
> Components: WS
> Affects Versions: 2.1.1.CR1
> Reporter: Balazs Pataki
> Assignee: Jozef Hartinger

> 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.
> This is my patch that worked in my setup:
