          Description

          Several issues have surfaced where if you have a Spring hosted service extending ViewHelperService that does not specify a separate interface, then the methods in that extension will be accessible locally but will not be on the server. This sounds like a local configuration issue, which if left alone, could result in other inadvertently bad code going out into the wild.

          One particular case of this was KULRICE-13118 where when we specified LabsTravelAccountLookupableImpl as a Spring service with #getService, we got an error saying it could not find the method allowsMaintenanceNewOrCopyAction which was not specified on the base LookupableImpl. I fixed it by adding the methods to the interface. There was also a similar case in KULRICE-13115, which I solved in the same way. That one is a bit easier to play around with since it doesn't have methods required by KRAD, so it could be used as testing.

          It seems that whenever we load a service through the global resource loader, we get this error but only on the server. I would think this should fail locally since this case is using a proxy and Spring relies on interfaces to create correct proxies.

          KRAD Sample App Labs -> Configuration -> On this page, click Configuration with Spring Service Expression.
          Result: Stacktrace.

              For a test, I modified ComponentViewHelperServiceImpl to not implement ComponentViewHelperService and removed the override annotations. Ran a clean/install to rebuild the krad sample app war file. I copied the krad-sampleapp war file into a tomcat instance on my local machine and started the tomcat instance manually. The suggest lookup was working correctly. I also tried enabling dev.mode and krad.dev.mode and found the same results. Thanks.
