Now you are just being mean. MS SQL Server is not MS Access. It has
pretensions of being enterprise-class.

I assume this is just to make sure I am only doing the delete with the
save.
And it seems to have worked to clear up the NullPropertyExceptions -
more on this later. But now I'm getting a
MandatoryToManyRelationshipException validation error, and it's on a
relationship that is on an object that is itself the destination of a
required ToMany relationship of ManufacturingSchedule. Both of these
Relationships have cascade delete rules.
ManufacturingSchedule <->> ScheduledManufacturingOrderItem <->>
ScheduledManufacturingOrderItemRouting
So simply deleting a ManufacturingSchedule should delete every object
in the related object-graph, which could be literally hundreds of
objects. But that's the whole point of having the Cascade Deletion
rule. Right?
It's complaining about a ScheduledManufacturingOrderItem not having
any ScheduledManufacturingOrderItemRoutings. Ahg!
See stack trace below.

Hmmm.... There is a form on this page that allows you to create a
ManufacturingSchedule, but it is in it's own WOForm. I have three
forms on the page. One to search, one to create new
ManufacturingSchedules and one to Delete/Edit ManufacturingSchedules.
The Delete/Edit form surrounds a WORepitition of all the
ManufacturingSchedules that are the results of the search form.
Submitting one form on a page shouldn't submit them all, should it?
Be nice now, I'm at least trying out this whole "Web" application
thing... It's only taken you what? 4 years of badgering me about Java
Client. Don't scare me away now! :-P
