Frank,
Thank you! This is great feedback.
I was seeing a deserialization error recently as well and believed I
had fixed it. I made some optimizations to the serializer

Hi John,
Your mileage may vary, but I'm really not concerned about users
causing significant performance degradation by doing lots of null
edits. If that is happening, it's probably a user interface design
problem. The trivial solution is to write a jscript function that
sets a hidden

Slot associations appear to work reflexively, by the way.

Hi all,
I've recently come across Elephant and have been reading the manual (even
though it claims to be a bit stale). My approach is to read the manual and
then dig into the code to learn more details or discrepancies not
documented/updated on manual. In so far, I have a few questions I wonder if
