What does that dangling “because” refer to? I can’t make it out.

My previous comment where I said I was using it to show the “path” to the 
current NSTreeController selection. I create my own NSPathComponentCells by 
finding each treeNode between the root and the selection. The cell's 
representedObject is the NSTreeNode for that part of the “path” & the 
title/image comes from the [treeNode representedObject], and the IBAction uses 
[clickedPathComponentCell representedObject] to find it.

   NSIndexPath *iterationPath = [[self.treeController selectionIndexPaths] 
firstObject];
   NSMutableArray *pathComponentArray = [NSMutableArray array];
   NSTreeNode *topNode = [self.treeController arrangedObjects];

   while ([iterationPath length] > 0) {
      NSTreeNode *treeNode = [topNode descendantNodeAtIndexPath:iterationPath];
      [pathComponentArray insertObject:[self componentCellFromNode:treeNode]
                               atIndex:0];
      iterationPath = [iterationPath indexPathByRemovingLastIndex];
   }
   [pathControl setPathComponentCells:pathComponentArray];
