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. The relationship is lazy, and when a dashboard is
accessed I get the expected "ItemPendingError" but then immediately
afterwards I get this java class-cast-exception on the server.
I can load the dashboards separately, but when accessed across the
relationship I get this error. Below is the relationship from the
data-management-config, and my Hibernate relationship mapping, and the
exception and debug trace follow that.
Thanks for any help you can provide. Is this a defect?
