Here is my .jsp file from where this is originated...

My gateStyle bean and my gate bean is annotation with @Id fields correctly. My
components.xml is I believe correct:
| <?xml version="1.0" encoding="UTF-8"?>
| <components xmlns="http://jboss.com/products/seam/components"
| xmlns:core="http://jboss.com/products/seam/core"
| xmlns:persistence="http://jboss.com/products/seam/persistence"

| <component name="org.jboss.seam.ui.EntityConverter">

Here is my persistence.xml for safe measure:

| <persistence>

| <jta-data-source>java:/amazinggatesDS</jta-data-source>

| </properties>
| </persistence-unit>
