Problem with FocusIn

[Eric Chatonet]

Hello Claus,

I think you are right when wanting to use closeField.
In the script of the card:

local lChangedFlag -- local script variable
on closeField
   put true into lChangedFlag
   -- will be set to true for any change in any field in the card
end closeField

on closeCard
   if lChangedFlag then <save>
   put false into lChangedFlag
end closeCard

Best regards from Paris,
Eric Chatonet.
