Re: [jboss-dev] Deployment chains

Another runtime view is what the source of an attachment is involved in the chain: PredeterminedManagedObjects TransientManagedObjects TransientAttachments and ideally which deployer set the current attachment at each level. This relates to tracking whether the correct attachment is being used when the profile service sets a PredeterminedManagedObject.
