I use a "form lock" user variable.
When submitting forms, I always have a form, a form confirmation page and
then the actual insert. What I do is set the "Form Lock" user variable on
the first action to "Start Thingy". The last action before the form is
inserted/updated is to set the same variable to "Finish". I put the
"formlock" assignment and the insert/update within a condition statement If
"Form Lock" = "Start Thingy" then ..... This prevents the user from re
inserting stuff by hitting the back button.
I re-use the same user variable over and over to save memory. I always set
the "Form Lock" to something unique to that taf. I also set the "form Lock"
always to "finish" when the insert/update is complete.
Is this the most efficient way of doing things? I always reuse the same user
variable so there is not any memory issues.
What do other people do to prevent the double insert.
Jose
