Mantain value when refreshing LOV because cascading parent item changed

gerardotin Public · Jan 5 2026

Idea Summary
An item LOV can be configured to have a cascading “Parent Item”.
When the Parent Item changes, the LOV is refreshed, and the current value is lost, event when the current value exists in the newly refreshed LOV.

Use Case
Whenever any hierarchical data needs to be selected, and values that exists in "level 2" can have several “level 1” values. 

For example, this set of values:

Level 1 (parent item): L1_A, L1_B, L1_C.

Level 2 (cascading LOV): L2_A (L1_A), L2_A (L1_B), …

In this case, when the “level 1” item is changed, the value of the cascading item is lost, and needs to be re-selected, either manually or through a programatic AJAX call.

Preferred Solution (Optional)
It would be nice to have an item property that enables to mantain selected value if exists in the newly refreshed LOV.

We reviewed this idea carefully, and while it was interesting, we concluded that it is unlikely to make its way into APEX in the foreseeable future.

    @gerardotin : meanwhile, with current APEX features, maybe you can utilize the Default Value for this depending on your situation. Upon parent change, the level 2 value is reset to the default value, so if you can collect the value by query you could configure Default Value like in this example.
