We have a SwitchYard application with a bean service implementing a Java interface. The interface has 4 methods, none of which take a parameter. We have promoted this service and applied an SCA binding. This results in the following error in the tooling.
"The referenced Java interface for service "BeanService" specifies more than one operation and the binding "sca1" does not specify which to use in the operation selector."
See the attached screenshot for details.
