Jeff, thanks for the info. I had already implemented a "work-around" where I stored the IDs from the header of the application's load, and when I need the dashboards I load them by ID myself.
I can try turning on auto-sync as a workaround also. Just curious... We've discovered several defects in FDS and Managed objects/relationships... Is there any timeline for when a bug-fix release might be available? thanks, Thunder --- In flexcoders@yahoogroups.com, "Jeff Vroom" <[EMAIL PROTECTED]> wrote: > > This does look like a bug that will occur when you have > autoSyncEnabled=false and you use a Set either with lazy loading or as a > return value from a fill. > > > > It is an easy fix - we are just casting to a List in a couple of places > instead of to a Collection.
