My domain/model/dto object starts as
public class FacilityAdminDto {
private Facility facility;
private Set<Platform> platforms;
and then it has the usual getters and setters.
The jsp that's setting this has for the platforms part
<table cellspacing="0" class="platformsAdd">
<c:forEach var="platform" items="${actionBean.platforms}">
<tr>
<td>
${platform.name}
</td>
<td>
<stripes:checkbox
name="facilityAdminDto.platforms"
value="${platform.id}"
/>
</td>
</tr>
</c:forEach>
</table>
The action bean has a getter for platforms; it's getting them from a database.
When I view the source html the platform name and id are correct.
The platform id is of type com.google.appengine.api.datastore.Key so I have
registered a TypeConverter and Formatter for it; its relevant code is
public class KeyConverterFormatter implements TypeConverter<Key>,
Formatter<Key> {
private final transient Logger log = LoggerFactory.getLogger(getClass());
@Override
public Key convert(final String input, final Class<? extends Key>
targetType,
final Collection<ValidationError> errors) {
this.log.debug("input: {}", input);
return (KeyFactory.stringToKey(input));
}
@Override
public String format(final Key key) {
this.log.debug("key: {}", key);
return (KeyFactory.keyToString(key));
}
KeyFactory is a google gizmo to fiddle with Keys.
My problem is that when Stripes is calling the FacilityAdminDto's setPlatforms,
the Platform object it has created has its name set to the stringified id
that's in the jsp, the value= part of the checkbox. As far as I can tell it's
because it's calling a Platform constructor that takes a string arg (it has
several constructors)
public Platform(final String _name) {
this(_name, 0);
this.log.debug("creating with name: {}", _name);
}
public Platform(final String _name, final int _ordinal) {
this.name = _name;
this.ordinal = Short.valueOf((short) _ordinal);
}
In my logs I can see the debug log statement; I never call that constructor.
In my logs the toString for FacilityAdminDto also shows that the Platform Set
has Platforms with their names set to the id string that was in the jsp.
If I comment out that constructor (and fix my test code to use the one that
specifies an ordinal), then it still tries to call it but gets an exception
