Why not? It is the easiest way to do that.

Otherwise, check input string in the WHEN-VALIDATE-ITEM trigger. This time you'll have to do it by yourself (i.e. code any logic you are interested in).

As Forms itself isn't capable of notifying you that inserted character is invalid (as soon as it is entered) (unless WHEN-VALIDATE-ITEM trigger fires), you'll probably have to do that with some Java code.

In the WHEN-VALIDATE-ITEM trigger? Well, you might try to use regular expressions (if possible), TRANSLATE and/or REPLACE functions, LOOP through the whole string and check character by character ... There have been quite a few discussions about such an issue in our SQL & PL/SQL forum so - take a look.

If you are talking about Java, sorry - I wouldn't know.
