>             Project: Hibernate3
>          Issue Type: Bug
>          Components: core
>    Affects Versions: 3.2.3
>            Reporter: Reto Urfer

> The following code block will throw a NullPointerException when targetComponentValues  should be determines and target[i] contains a NULL value.
> 			else if ( types[i].isComponentType() ) {
> 				// need to extract the component values and check for subtype replacements...
> 				AbstractComponentType componentType = ( AbstractComponentType ) types[i];
> 				Type[] subtypes = componentType.getSubtypes();
> 				Object[] origComponentValues = original[i] == null ? new Object[subtypes.length] : componentType.getPropertyValues( original[i], session );
> 				Object[] targetComponentValues = componentType.getPropertyValues( target[i], session );
> 				replaceAssociations( origComponentValues, targetComponentValues, subtypes, session, null, copyCache, foreignKeyDirection );
> This problem can be fixed the same way as it is prevented when origComponentValues are determined (see following line)
> Object[] targetComponentValues = target[i] == null ? new Object[subtypes.length] : componentType.getPropertyValues( target[i], session );
> 				copied[i] = target[i];
> 			}
> The problem did not exist in Version 3.2.2
