David Hittner commented on XDT-1513:
------------------------------------
Thanks for the fix, Paul ! That takes care of most cases, but not all. Consider:
The classes in question are:
/** @hibernate.class */
Class WaypointHistory {
List waypoints;
/** @hibernate.list table="waypoints"
* @hibernate.collection-key column="id"
* @hibernate.collection-index column="indx"
* @hibernate.collection-composite-element class="Waypoint"
*/
public List getWaypoints() { return waypoints; }
/* there are more properties, I just didn't note them */
}
Class Waypoint {
Location loc;
Date time;
/** @hibernate.component */ <--- potential change to
@hibernate.nested-composite-element
public Location getLocation() { return location; }
/** @hibernate.property */
public Date getTime() { return time; }
}
Class Location {
Double latitude;
Double longitude;
/** @hibernate.property */
public Double getLatitude() { return latitude; }
/** @hibernate.property */
public Double getLongitude() { return longitude; }
}
The problem is that I cannot change the @hibernate.component to
@hibernate.nested-composite-element on the Location property in the Waypoint
class, because I need to have a Waypoint as a property (component) of yet
another class:
/** @hibernate.class */
Class Truck {
Waypoint lastLocation;
/** @hibernate component */
public Waypoint getLastLocation() { return lastLocation; }
}
The parser really needs to be able to understand that if we are persisting a
component that has components, that the multilevel @hibernate.component tag
needs to be dynamically replaced with a @hibernate.nested-composite-element tag.
Should I resubmit this as a new bug number, or do you want to reopen this one?
Thanks!

> Project: XDoclet
> Type: Bug
> Components: Hibernate Module
> Versions: 1.2.3
> Environment: Windows XP SP2
> Eclipse 3.1.0
> XDoclet 1.2.3
> Reporter: David Hittner
> Assignee: xdoclet-devel (Use for new issues)
> Fix For: 1.3
>
>
> I have created a class which needs to store a List of Components containing a
> component.
> The generated classfile.hbm.xml generates the List part correctly, and the
> first-level component
> correctly (as a composite-element), but the second-level component is
> incorrectly tagged with <component> rather than
> <nested-composite-element>, so Hibernate v3.0 fails to map the class at
> runtime..
> Hibernatedoclet in Xdoclet 1.2.3 generated the following code:
> <list>
> <composite-element class="test.component"
> <component class="test.nested_component">
> ...
> </component>
> </composite-element>
> </list>
> As far as I understand, it needs to generate (which works):
> <list>
> <composite-element class="test.component"
> <nested-composite-element class="test.nested_component">
> ...
> </nested-composite-element>
> </composite-element>
> </list>
