Catalog item reference variable value not displayed in the portal cart

[s_thore]

Hi,

Everything I describe below is on the service portal, but I can't find portal in the topics list.

I have a catalog item with a reference variable. The available values for this variable are filtered depending on the answer to another variable, through the following scripted reference qualifier :

javascript:"assigned_to="+current.variables.u_requested_for

It works as expected when I create a new item and fulfill the u_requested_for field first, but if I add the new item to the cart, then edit the cart item, the reference variable field is displayed empty. As it's a mandatory field, it's cicrcled in red and listed in the "Required information" frame.
When editing the cart item, if I re-select a value in the field, then click "update cart", the field will be displayed empty again after reloading the page.

If I add logs in the server script of the catalog item widget, I see that the field contains a sys_id, but somehow this sys_id cannot be used by the widget. The RITM has a value for the variable, so it's a matter of displaying the value on the portal, not storing it in the database.

The catalog item widget is a clone of the oob widget with ID=widget-sc-cat-item-v2.

I guess the cause is related to the javascript reference qualifier, as other reference variables on the same cat item, without javascript qualifiers, work correctly, and I encounter the same incident on other cat items with reference variables using javascript ref.qual.

How can I have the name of the referenced object in the field, when editing the item in the cart ?
Do I have to add a script for every reference field with scripted ref.qual, in the catalog item widget ?

Thank you for reading.

I get the same issue with a select box that I am populating with addOption.  Displays OK when editing the cart in UI16, but goes blank when editing the cart item in the portal
