hi i have a table called equipment containing engine_type_id.
in the equipment form that is based on the equipment table, i added a non database item called engine_type.
i added an LOV for the engine type field, so that the user can choose the engine type from the the egine types table. i made the engine type id hidden. and set the validate item from LOV to yes.
on post query trigger, i selected the engine type into the nondatabase field.
the form is working properly.
when i push CTRL F11 (query) and scroll, even if i didnt change anything the form builder asks me , do u want to save changes.
how can i solve this issue..
thank u

Because you changed the item in post-query that caused the LOV validation to fire. This caused the engine_type_id to be marked as changed (even though the value was the same). This causes the record to be marked as changed and so the save changes message.
Use
set_item_propery(<engine_type>, item_is_valid, property_true)
In the post-query trigger after you set that item to avoid the validation firing.
You should use that set_item_property whenever you set an item in post-query.
