I agree with Ryan. An old rule from way back:- Pass Keys Round Not Data
It's simpler to only keep keys across user interactions (either stored on the form or in the session). Otherwise you have 3 versions of data 1 - what's on the database. 2 - what you've saved in the session (or on the form) 3 - new values coming in from the form Not having the 2nd set of data is a big simplification. Some might say re-reading the database more frequently is inefficient. ie. Your database caching is less efficient than your server's caching of session info. Maybe - but can serializing data to the client form be faster than you DB?.
