[jboss-dev-forums] [Design of JBoss jBPM] - Identity module constraint needed

[david.lloyd@jboss.com]

It looks to me like there ought to be a unique constraint across either the GROUP_ and ROLE_ columns or just the GROUP_ column within the identity JBPM_ID_MEMBERSHIP table.

The effect would be to prevent a user from being in the same group more than one time, or barring that, require that each membership within the same group has a unique role.

Agree/disagree?
