Hi Mark,
Oh man! All that code reduced to:
NSMutableArray favourites;
public ElementSearch(WOContext context) {
super(context);
favourites();
}
/** @TypeInfo Element */
public NSMutableArray favourites() {
if (favourites == null) {
favourites = (NSMutableArray)user.favouriteElements();
}
return favourites;
}
public boolean elementChecked()
{
return favourites.containsObject(anElement);
}
public void setElementChecked(boolean newElementChecked) {
// Jerry Walker's code:
// is the element already in the favourites?
boolean oldValue = elementChecked();
// if selected, and not already in the favourites list, add it
if (newElementChecked && !oldValue) {
user.addObjectToBothSidesOfRelationshipWithKey(anElement,
"favouriteElements");
}
// if not selected but already in the favourites list, remove it
else if ( !newArtifactChecked && oldValue) {
user.removeObjectFromBothSidesOfRelationshipWithKey(anElement,
"favouriteElements");
}
}
public WOComponent submit()
{
Session session = (Session)session();
EOEditingContext ec = session.defaultEditingContext();
ec.saveChanges();
return null;
}
Where do I send the beer??
I didn't realize that I could cast the NSArray user.favouriteElements
() to NSMutableArray. That was pretty much the key. NOW it's FAST!
Thanks so much,
David

you should be able to directly use user.favouriteElements() instead
of going through selectionList. In other words, elementChecked and
setElementChecked can directly work on userFavouriteElements().
