From the thread i concluded that..
.It is important to use the following in the POST-QUERY TRIGGER as follows
SET_RECORD_PROPERTY(:SYSTEM.TRIGGER_RECORD, :SYSTEM.TRIGGER_BLOCK, STATUS, QUERY_STATUS);
BEGIN
SELECT dept_name
INTO :dept_name
FROM departments
where dept_id = :emp.dept_id;
EXCEPTION
WHEN OTHERS THEN MESSAGE(ERRMSG);
END;From the code you show, not really. The exception-part is even bad, leave it out, forms will show an error anyway when it occurs.
This part
SET_RECORD_PROPERTY(:SYSTEM.TRIGGER_RECORD, :SYSTEM.TRIGGER_BLOCK, STATUS, QUERY_STATUS); CAN be useful, but is not u MUST. In any case, it should be after any lookup-code, so in your example it should be just before the exception handler.
The SET_RECORD_PROPERTY makes sure that any outstanding validation on any item of the current record will be considered as "finished". This is helpful when you have a lookup-code as in your example AND if there is a validation-trigger on that lookup-item (in your case a WHEN-VALIDATE-ITEM-trigger on :DEPTNAME), which checks the value in the item and tries to read the according fk-id-value for the given textvalue and store it back to the fk-id-column.
