XMLDirectMapping - No conversion value provided

Question

docx4j (which I host) is typically used with the Sun/Oracle JAXB implementation; the classes of interest below were generated using XJC. Following on from an earlier issue which the MOXy guys kindly fixed, I'm continuing to try to get it working with EclipseLink MOXy. With a particular DOM document, I'm now getting: ``` [Exception [EclipseLink-25004] (Eclipse Persistence Services - 2.4.0.v20120529-r11529): org.eclipse.persistence.exceptions.XMLMarshalException Exception Description: An error occurred unmarshalling the document Internal Exception: Exception [EclipseLink-116] (Eclipse Persistence Services - 2.4.0.v20120529-r11529): org.eclipse.persistence.exceptions.DescriptorException Exception Description: No conversion value provided for the value [1] in field [@ns1:val].

Accepted Answer

Note: I'm the EclipseLink JAXB (MOXy) lead an a member of the JAXB (JSR-222) expert group. The XML document being unmarshalled is actually invalid. If the value in the `ns1:val` attribute is changed to match the allowed enum values then everything works as expected. XML File Line 95 of the xml doc is this ``` ``` STOnOff 1 is not a valid value...should be "on" or "off" ``` @XmlType(name = "ST_OnOff") @XmlEnum public enum STOnOff { @XmlEnumValue("on") ON("on"), @XmlEnumValue("off") OFF("off"); private final String value; } ``` CTRadPr ``` public class CTRadPr implements Child { protected CTOnOff degHide; protected CTCtrlPr ctrlPr; ... } ``` CTOnOff ``` @XmlType(name = "CT_OnOff") public class CTOnOff implements Child { @XmlAttribute(namespace = "http://schemas.openxmlformats.org/officeDocument/2006/math") protected STOnOff val; ``` There is a bug in MOXy related to handling the invalid value. What MOXy should do is when it spots the invalid value it should report an error to the `ValidationEventHandler`. If the `ValidationEventHandler` handles the event then a value will not be set for the corresponding field/property. When you try this with the JAXB RI you will see that the invalid values are not populated in the object model You can use the following bug to track our progress on this issue: - http://bugs.eclipse.org/381217 UPDATE We have fixed bug 381217 in the EclipseLink 2.4.0 stream. You can download a nightly label from the following location: - http://www.eclipse.org/eclipselink/downloads/nightly.php Note: With the fix, MOXy will report a validation event for the invalid attribute value just as it would for an invalid element value. This is different) behaviour from the JAXB-RI which throws validation events for invalid elements but not invalid attributes. I believe the RI behaviour is a bug.
