I ran into an issue packaging an application today that turned out to be the result of a change in the EsParsing application's #loaded method, which is ultimately called by EmSystemConfiguration>>#xdImageInitialize. As of VA 8.0.2, EsParsing class>>#loaded sends #defined, which is a method in the SubApplication class, but in the application EmImageSupport.
In order to package correctly, the EmImageSupport application needs to be included in the package. Ideally, I think EsParsing should require this application as a prerequisite, since it's now relying on a method from that app. My temporary workaround is to include both applications as prereqs of my own app instead of just EsParsing.
