Some changes have been made today to dedicated services that will probably break your RUI applications.
The call statement was updated not too long ago to support a new "using" clause, where you specify a variable that tells the call how to reach the service. A new type "HttpProxy" has been added to the system parts which you can specify for the using clause when invoking a dedicated service. The DedicatedService annotation has been removed, and you must now use the using clause, passing in an HttpProxy.
Old syntax: serviceVariable MyService{@DedicatedService}; call serviceVariable.functionName() returning to handleResponse onException serviceExceptionHandler;
New syntax (two usages): When referencing a service part the HttpProxy doesn't need anything set in the variable: call MyService.functionName() using new HttpProxy returning to handleResponse onException serviceExceptionHandler;
When referencing an interface part you must specify the implementation name: http HttpProxy = new HttpProxy("server.MyService"); call IMyService.functionName() using http returning to handleResponse onException serviceExceptionHandler;
