Add this to your category on NSTreeController. It calls the -
flattendedNodes method I gave you earlier.  You can then get the tree 
node for the whatever you added to the tree and call NSOutlineView's -
rowForItem:

- (NSTreeNode *)treeNodeForObject:(id)object;
{    
   NSTreeNode *treeNode = nil;
   for (NSTreeNode *node in [self flattenedNodes]) {
       if ([node representedObject] == object) {
           treeNode = node;
           break;
       }
   }
   return treeNode;
}
