Why the Need for a ltCF_FormSavegt ?

• Needed a usable way to prevent users from
  submitting forms that had not changed
• Needed to be generic (for all forms)
• Needed to be fast (client side??)
• Couldnt be too complex for other team members to
  implement on their forms

5
Options Available?? (Analysis)

• Triggers in Database
• Too cumbersome
• Server Trip Required
• Have to be coded for each proc/insert
• Cold Fusion
• Server side (not fast)
• Generic?? Not really
• Other Options?
