This function sets both the display & return value of the Popup LOV. If there are any items in the "Additional Output" attribute, they will also be set with the correct values.
Important Note: this feature only works with a Popup LOV whose source is a dynamic "List of Values" (based on an SQL query)
In the below example you can see the following behaviour:
- the slider values correspond to the Customer ID's
- on change of the slider, we are calling the API function on the "Customer" Popup LOV with the selected ID value
- the popup LOV is then set with the correct display & return value
- all the "Additional Output" item values are updated on change as well
