URGENT : List Of Values Validation problem

Question

Hello
I want to restrict my object(textfield) to not validate my LOV(List of Values) on certain values such as if the textfield contains the value 'ALL' the LOV should not be validated and if the textfield contains value other than 'ALL' then the LOV should vaildate...
Kindly guide me through this if any one knows what textfield trigger should i use or any other way is required for this purpose.
Thanx.

The 'right way' to emulate LOV validation is to do the following:
Set autoskip on in your item, since you want focus to move to the next item.
Set LOV validation to NO for the item.
Write a When-validate-item trigger to do this:
If the value = 'ALL' or value is null then exit.
For the record group attached to the LOV:
If the record group is not populated, then populate it.
Loop through the record group to find a value matching the value entered. If one is found then exit.
If a value is not found, use show_lov to display the LOV.
If the user selected a value, then exit.
If user did not select a value, issue an error message, raise form_trigger_failure.
