In my form i need to validate two text fields. the validation process includes null checking and special character checking..and i used key-next-item trigger to validate the text field n it is working..when i press tab key the validation is working but when i use mouse to navigate the text fields the validation is not working...any suggestion..
If validation is successful, you'll easily navigate to the next item. Just press TAB, Enter or click with the mouse - do not use GO_ITEM (but you've already seen that - it is a restricted procedure and can not be used in WVI trigger). If it is not successful, raise an error and you'll stay in current item.
Once again: item validation is to be done in the WHEN-VALIDATE-ITEM trigger.
