Answer 1

When your endpoint 1 is inactive it returns a soap fault and you want it to go to the fault sequence. But at the moment that fault sequence is considered as a response and it is sent to the client (soap ui).

In WSO2 ESB 4.5.0 onwards, there is a new property FORCE_ERROR_ON_SOAP_FAULT added. By setting this property, soap faults will be directed to fault sequence. You can do your next logics when you are in the fault sequence (for example invoking another sequence).

Refer [1] for a sample proxy service.
