    <p>I have the following <code>Enum</code> Class:</p> <pre><code>@XmlJavaTypeAdapter(value = PastMedicalHistoryAdapter.class) public enum PastMedicalHistory { Diabetes, Obesity, Smoking, COPD, CAD, PVD, Other }</code></pre> <p>and Generic Adapter:</p> <pre><code>public abstract class GenericEnumAdapter&lt;T extends Enum&gt extends XmlAdapter&lt;String, Enum&gt; { @Override public Enum unmarshal(String v) throws Exception { log.info("unmarshal: {}", v); return convert(v + ""); } public abstract T convert(String value); @Override public String marshal(Enum v) throws Exception { log.info("marshal: {}", v.name()); String s = "{\"" + v.name() + "\":" + true + "}"; return s; } }</code></pre> <p>and basic implementation with </p> <pre><code>public class PastMedicalHistoryAdapter extends GenericEnumAdapter&lt;PastMedicalHistory&gt; { @Override public PastMedicalHistory convert(String value) { return PastMedicalHistory.valueOf(value); } }</code></pre> <p>and I used it like this:</p> <pre><code>@Data @XmlRootElement(name = "Patient") public class Test { private List&lt;PastMedicalHistory&gt; history; public static void main(String[] args) throws Exception { JAXBContext cxt = JAXBContext.newInstance(Test.class); Marshaller mar = cxt.createMarshaller(); mar.setProperty(javax.xml.bind.Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE); mar.setProperty(JAXBContextProperties.MEDIA_TYPE, "application/json"); mar.setProperty(JAXBContextProperties.JSON_INCLUDE_ROOT, Boolean.FALSE); Test t = new Test(); t.setHistory(Arrays.asList(PastMedicalHistory.CAD, PastMedicalHistory.Diabetes)); mar.marshal(t, System.out); } }</code></pre> <p>the problem, is Output for history is always null like this:</p> <pre><code>[exec:exec] 2013-09-29 12:13:18:511 INFO marshal: CAD 2013-09-29 12:13:18:522 INFO marshal: Diabetes { "history" : [ null, null ] }</code></pre> <p>I'm using Moxy <code>2.5.1</code> as <code>JAXB</code> Provider, so What I'm missing, or what I'm doing wrong?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
