Everything works fine, no need for [reloadData] - no need for unnecessary references to the PXSourceList instance, if you create your list of Source Items during [init*].
EXCEPT ... if you return "TRUE" / "YES" from isGroupAlwaysExpanded, then the group shows up with "zero" items, and no expansion triangle.
Doing an extra [sourcelIst reloadData] during awakeFromNib worksaround the problem, but AFAICS it shouldn't be needed and this causes the data to get loaded twice, unnecessarily.
