Oracle Forms

Hi. I'm finding I can't use the Go_Item function in a When-Validate-Item Trigger because it's a restricted trigger. Is there a common method for firing a trigger that I can use to validate an item (similar to the When-Validate-Item trigger) that is not restricted where I can use built-ins like Go_Item, Go_Block, etc.... I would use the Key-Next-Item trigger, but it doesn't fire when a user mouse clicks outside of the item I need to validate.

I need to fire a validation on an item which identifies if certain values have been entered. If I find certain values then I need to navigate to a 'Problems Log' block where the user can fill out a problem record. Upon leaving the 'Problems Log' block I then need to return to the previous block and let the user continue entering items. All this navigation seems to be restricted in the When-Validate-Item trigger.

Any help would be greatly appreciated.
