This sounds much like the problems I have been having where context changes unexpectedly during a series of actions. I’ve also seen this running javascript as a mass action against selected rows, except maybe the reverse of Joe’s issue. I could run the js against the selected rows if I invoked it from a Button Set button of type Custom: Run Skuid Snippet. It failed (or maybe only affected one row) if the button type was Run Multiple Actions and called the same snippet. The code inside the snippet is getting arguments[0].component.context.rows, which I can walk as an array. I’m suspecting Joe is losing the context of his Account record when an array of selected Accounts is created.
Joe, do you set the Account date field before, or after, you create the cases?
