HornetQ children JMS Queue, JMS Topic, Connection Factory) all have a list box to pass jndi names. Due to Bug 815305 , the UI can not enforce that at least 1 jndi name is given, so that the user can actually pass 0 entries without being warned. This condition is caught after submit and the create resource request will fail. Same applies to configuration update For connection factories, there is a connector element with two properties - name -- required - backup -- optional The name is required. For whatever reasons, the UI can not enforce that this is needed on child resource creation. The presence of the name is enforced at plugin level. If no name is given creation will fail with an appropriate error message. For configuration updates, this is no issue.

This has now changed slightly for connection-factories: "backup" for the connector is no longer shown in the UI. As the UI can not enforce that exactly one of connector and discovery-group-name are present, the plugin enforces this and reports appropriate errors.

as talked to Deon, marking this back to on_dev to add info into regular docs.
