It seems that the further I get into CF9's Air/Orm stuff, the more roadblocks I find.  I guess this is to be expected with a first generation feature, but that doesn't make it any less frustrating - especially when you can't seem to get any community support and there is very little documentation. I did just get a verified bug email from adobe for my bug on self joins, thanks Adobe!

Ok, got that out of the way.  Now to the problem.  When you define an entity with relationships in the CF9/Air orm and perform a fetch to retrieve the server's data for that entity the fetch call returns the parent entity data as well as all of the related entity data.  However, when you perform the saveUpdateCache with that result you'll find that it doesn't quite work correctly.

To explain this better, let me give a real example from my project (scaled down a bit for clarity):

Ok, today has just been one of those days.  The culmination of many hours of testing, rewriting and testing again is starting to pinpoint some things that have been very flaky and difficult to debug in the CF9 Air offline integration mix.

One particularly difficult one I have been debugging is that in certain cases the adl.exe process does not stop when I quit the debugger or close the Air app if not in debug run mode.

I am spending a lot of time trying to figure out how this ORM stuff works on the Air side of things.  The lack of documentation makes it very difficult to determine if a problem I am encountering is a bug, or an error in how I have something implemented.

In this case, I think it is a bug (which I will log with the Adobe bug tracker).  It has to do with recursive self joins (I'm sure there is a much cooler sounding name for it, but that's all I've got).  Here's an example of what I mean.
