[Jason Porter (JIRA)]

    [ https://issues.jboss.org/browse/SEAMPERSIST-53?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12609968#comment-12609968 ] 

Jason Porter commented on SEAMPERSIST-53:
-----------------------------------------

Yes, you can remove the @RequsetScoped or @ConversationScoped (this is telling Seam Persistence what you want the EntityManager to be scoped), but your entity manager will be DependentScoped. You may not see a lot of problems, but in a web app you may have to do some extra merge() operations because your transaction manager will no longer be around and any entities will have been detached.
