patches with duplicate element patch-id values should be rejected ----------------------------------------------------------------- Key: WFCORE-687 URL: https://issues.jboss.org/browse/WFCORE-687 Project: WildFly Core Issue Type: Bug Components: Patching Affects Versions: 1.0.0.CR2 Reporter: Alexey Loubyansky Assignee: Alexey Loubyansky Fix For: 1.0.0.CR4, 2.0.0.Alpha1 Patches that contain duplicate patch-id attribute values in 'element' elements in patch.xml can be applied but can't be rolled back. An attempt to rollback such a patch will result in an error "Content loader already registered for patch " + patchID, thrown from IdentityPatchContext.recordContentLoader(patchID, contentLoader). Current implementation should reject patches with duplicate element patch-id values (unless the value is 'base'). Adding support for duplicate element patch-id values is a more difficult task at this point. If we decide to support it after all, it'll be implemented under a different issue.
