Subclassed entities: java.lang.IllegalArgumentException: Unknown entity
I have a 3 level inheritance hierarchy where writing out the subclassed entity throws: java.lang.IllegalArgumentException: Unknown entity
My classes are defined as:
Top level :
Code:
@MappedSuperclass
public abstract class AbstractContentRecord {
2nd level, used by another app, works fine:
Code:
@RooJavaBean
@RooToString
@RooEntity
public class Widget extends AbstractContentRecord implements WidgetInterface {
3rd level, used as CmWidget, fails on merge() with stack trace below:
Code:
@RooJavaBean
@RooToString
public class CmWidget extends com.foo.content.common.domain.catalog.Widget {
The Widget I'm extending resides in a dependent maven project.
I do have this project defined as a weave dep:
Code:
<weaveDependency>
<groupId>${project.groupId}</groupId>
<artifactId>content-common</artifactId>
</weaveDependency>
In my controller I call a factory method to instantiate the right type of widget so I can use the same controller for both the parent and child class entities:
Code:
@RequestMapping(value = "/", method = RequestMethod.POST)
@ResponseBody
@ResponseStatus(HttpStatus.CREATED)
public WidgetDTO createWidget(
HttpServletRequest request,
@Valid @RequestBody WidgetDTO transferObject) throws DuplicateEntityException {
Widget widget = entityFactory.makeWidget(); // <<- factory method does return a CmWidget.
widget.toEntity(transferObject); // pull fields from DTO into entity, verified all fields OK.
widget = widget.merge(); // <<- FAILS HERE
At runtime when calling entity.merge() to save a new subclassed entity I get:
Code:
org.springframework.dao.InvalidDataAccessApiUsageException: Unknown entity: com.foo.content.manager.domain.catalog.CmWidget; nested exception is java.lang.IllegalArgumentException: Unknown entity: com.foo.content.manager.domain.catalog.CmWidget

I'm completely stuck on this. Any pointers would be greatly appreciated.
