With one Petals ESB node on which the following SU are deployed:
a SU 'A' providing: Itf1/Svc1/EP1
a SU 'B' providing: Itf1/Svc1/EP2
a SU 'C' consyuming: Itf1/Svc1/EP1
When invoking the service Itf1/Svc1 through SoapUI, the endpoint EP1 is correctly invoked.
If you undeployed SU 'A', the next SOAP UI invokation will be redirected on the EP2, that is wrong: on error should occurs.
