Entity command should provide an option for using a Mapped Superclass --------------------------------------------------------------------- Key: FORGE-133 URL: https://issues.jboss.org/browse/FORGE-133 Project: Forge Issue Type: Enhancement Components: Builtin Plugins, Java EE APIs Affects Versions: 1.0.0.Alpha4 Reporter: Lincoln Baxter III Priority: Optional Fix For: 1.0.7.Final Instead of putting version and ID in the entity itself, the entity command should allow for using a Mapped superclass (hopefully trying to check for version and id in the process, so that those fields may be omitted from the entity itself.) {code} /* * Copyright 2010 - Lincoln Baxter, III (lincoln(a)ocpsoft.com) - Licensed under the Apache License, * Version 2.0 (the "License"); you may not use this file except in compliance * with the License.
