Whenever you try to get a PropertyEditor for something but none is there, do the following additional check:

if (type.getSuperclass().getName().equals("java.lang.Enum"))
{
editor = new EnumPropertyEditor(type);
}

where the EnumPropertyEditor is:

public class EnumPropertyEditor extends PropertyEditorSupport implements PropertyEditor
{
private final Class targetType;

public EnumPropertyEditor(Class targetType)

{ this.targetType = targetType; }

public void setAsText(String text) throws IllegalArgumentException
{
try
{
setValue(targetType.getMethod("valueOf",new Class[]

{String.class}

).invoke(null,new Object[]

{text}

);
} catch (IllegalAccessException e)

{ throw new IllegalStateException(e); } catch (InvocationTargetException e)
{ if (e.getTargetException() instanceof RuntimeException); throw (RuntimeException)e.getTargetException(); throw new IllegalStateException(e); } catch (NoSuchMethodException e)
{ String err = type.getName() + " does not contain the required method: public static " + type.getName() + " valueOf(String);"; throw new IllegalArgumentException(err,e); }

}

public String getAsText()
{

try
{ return targetType.getMethod("name",null).invoke(getValue(),null) } catch (IllegalAccessException e)
{ throw new IllegalStateException(e); }

catch (InvocationTargetException e)

{ if (e.getTargetException() instanceof RuntimeException); throw (RuntimeException)e.getTargetException(); throw new IllegalStateException(e); }

catch (NoSuchMethodException e)

{ String err = type.getName() + " does not contain the required method: public String name()"; throw new IllegalStateException(err,e); }

}
}
