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. For now, maybe you can workaround the problem by turning autoSyncEnabled=true?

The "bug report" form is very lacking though! It said my description had to be less than 2000 characters, which isn't enough to provide the trace information, or the Hibernate/FDMS mappings, and then I trimmed and trimmed my bug report to 1931 characters and it STILL wouldn't let me submit it... (last time I checked, 1931 was less than 2000)... so I yanked out MORE useful information until I could get it to submit. Does anyone at Adobe want to get the full scoop on this issue? Here it is! Please let me know if this has been captured, and if it is a known defect. thanks, Thunder --- In [email protected] <mailto:flexcoders%40yahoogroups.com> , "thunderstumpgesatwork" <[EMAIL PROTECTED]> wrote: > > Guys, > > I'm having more troubles with FDS... seems like there's some internal > exception lurking around every corner... > > Here's a simple managed relationship between an applicationConfig and > a Set of dashboards.
