I'm working on a specialized CAD program with a fairly complicated model, not using Core Data. The data is hierarchical in nature, but not homogeneously.
A "Part" in my app has a set of geometric primitives, and a set of labels (both have a common base class). These are two separate sets (arrays) on the part. But when editing the part, they can each be clicked on and edited. I want to use an NSArrayController to manage the selection, but I'm not sure of the best approach. Should I create a new property, a read-only array, that is generated on the fly as the union of the two above sets? In a different document/view, a part is a single entity whose geometry cannot be separately manipulated (although the labels can be moved around). I can imagine a few ways to handle this. I only mention it as a note to keep in mind. Further complicating matters is a need for an inspector palette (like IB's) that reflects the state of the current selection (with stacked views for various subclass properties). Suggestions?
