WARNINGYES

It's very easy to define a business rule: if such and such happens, then either: display an error message, display a warning message, send an email, send an SMS, open a task or send a push message (whatever that is). A warning message displays some text along with two buttons, "continue" or "cancel". I've never noticed until now that the default button is "continue". Thus it's very easy to consider the scenario whereby a user does something that causes a rule to fire, but the user ignores the warning message and simply presses "continue", thus basically negating the whole point of the warning.

I discovered (very belatedly) that there is a system constant, WARNINGYES, that controls which button is the default; 1, which is the predefined value, means that the "continue" button is the default, whereas 0 means that "cancel" is the default. I changed the value of the constant to 0 and now hopefully users will actually read any message displayed.

This is to a certain extent shooting myself in the foot: once every couple of days I have to create delivery notes from packing lists (don't ask), and when I paste an order number into the delivery notes screen, two or three messages are displayed. I don't read them and simply press enter to continue. Now I'm going to have to press an arrow key and then enter. The message are generally "Packing list X is connected to this order" and some text referring to the customer. Because I belong to the 'tabula' users group, I can't execute the privileges program, otherwise I would turn these warning messages off. Such are the tribulations of a system manager.

I made that change 20 minutes ago and no one has written to me about it yet. Normally a change like that gets noticed very quickly.
