Scott M Stark resolved JBMAN-77.
--------------------------------

    Fix Version/s: JBossMan.2.1.0.CR8
       Resolution: Done


Changes include:

public @interface ManagementProperty
{
...
   /** A string representation of the property default value if not empty
    */
   String defaultValue() default AnnotationDefaults.EMPTY_STRING;

A DefaultValueBuilder interface:
/**
 * Convert a string representation of a default value into a MetaValue
 * 
 * @author Scott.Stark at jboss.org
 * @version $Revision:$
 */
public interface DefaultValueBuilder
{
   public MetaType getType();
   public MetaValue buildMetaValue(String value)
      throws Exception;
}

and a DefaultValueBuilderFactory annotation:
/**
 * An annotation describing the DefaultValueBuilder implementation
 * for a property.
 * This can be used on fields, methods for an individual property
 * 
 * @author Scott.Stark at jboss.org
 * @version $Revision:$
 */
@Target({ElementType.METHOD, ElementType.FIELD})
@Retention(RetentionPolicy.RUNTIME)
public @interface DefaultValueBuilderFactory
{
   /** The constraints, allowed values populator factory */
   Class<? extends DefaultValueBuilder> value();
}

There are implementations of DefaultValueBuilder for all of the SimpleMetaTypes.

> One feature jon has is an ability to unset managed property values which essentially restores them to the component specfic default. We would need to pull the default values into the managed property layer so that when a property was removed, we can undo any updates to return the property back to is default value.
