[rules-users] Guvnor model with 'Comparable' not working

Hi everybody, I use Guvnor 5.4 and have a model which consists of classes and subclasses. @Entity public class TestClass { @Id private long id; @Embedded private TestEmbeddable embedded; } @Embeddable public class TestEmbeddable implements Comparable<TestEmbeddable> { @Column private String testProperty; @Override public int compareTo(TestEmbeddable o) {...} } Now, in Guvnor I use the guided Editor and create a new WHEN condition: There is a TestClass with: embedded ... Usually, when I click on "embedded", I can select Apply a constraint to a sub-field of 'embedded': Show sub fields ... This line does NOT show if that subclass (here: TestEmbeddable) implements Comparable. It does however work if I don't use Comparable or if I select TestEmbeddable directly (which I can't as I don't inject those into my working environment). Is this a known bug? I couldn't find anything about this.
