We are using something similar to CustomRepresentationService of todoapp, we use it to get a simple JSON representation.
Our CustomRepresentationService is annotated as DomainService, its package is registered in isis.properties (isis.services.ServicesInstallerFromAnnotation.packagePrefix but not in isis.services!) and it is located in the dom module.
With apache isis 1.7 it was working, now we migrated to isis 1.8 and now this causes an error during maven install:
WicketRuntimeException: There is no application attached to current thread main
When I run the application on tomcat everything seems to work, the UI is available and I can access the CustomRepresentationService through Rest API.
I did the described changes on the todoapp for isis 1.8 and I'm getting same result (I attached my changes with patch.txt).
I moved the CustomRepresentationService to dom module because I need an possibility to unit test the generated JSON strings.
Please fix that issue or assist me in creating a workaround.
