I tried to reproduce this, by introducing an error in the todo app,
changing one of the queries in ToDoItem:
@javax.jdo.annotations.Query(
name = "findByOwnedByAndCompleteIsFalse", language = "JDOQL",
value = "SELECT "
+ "FROM dom.todo.ToDoItem "
+ "WHERE ownedBy == :ownedBy "
+ " && complete = false"),
where "complete == false" has been changed to "complete = false".
In the Wicket viewer - as hoped - I got the error page with a big nasty
stacktrace that included:
javax.jdo.JDOUserException
Invalid operator "=". Did you mean to use "=="?
org.datanucleus.api.jdo.NucleusJDOHelper#getJDOExceptionForNucleusException(NucleusJDOHelper.java:549)
org.datanucleus.api.jdo.JDOQuery#executeWithMap(JDOQuery.java:351)
org.apache.isis.objectstore.jdo.datanucleus.persistence.queries.PersistenceQueryFindUsingApplibQueryProc
In the Restful viewer, when I invoked
http://localhost:8080/restful/services/ToDoItems/actions/notYetComplete/invoke
I got something an HTML error:
HTTP ERROR 500

So, I think the issue is that the Restful viewer, although it's throwing a
500 response error as expected, is also returning HTML rather than JSON
error page.
I've raised https://issues.apache.org/jira/browse/ISIS-966 for this.
