Jörg Rade commented on CAUSEWAY-3687:
-------------------------------------
Reproduce with causeway-app-simpleapp (jpa):
* add execute method to SimpleObjects:
{code:java}
@Transactional
public SimpleObject execute(SimpleObject obj) {
return obj;
}
{code}
Invocation of Prototyping -> Run Fixture Script lead to:
{code}
java.lang.NullPointerException: Cannot invoke
"org.apache.causeway.applib.services.repository.RepositoryService.persist(Object)"
because "this.repositoryService" is null
