Hi everyone :waving_hand:

I’m currently building a custom Dialog in Frappe that contains a Table field (using fieldtype: "Table") to display and edit alternative items in a Work Order form.

The dialog works fine — I can dynamically load data into the table and update fields like alternate_item, available_qty, and ratio.
However, I’m struggling with how to store and retrieve temporary variables (e.g. cached API data, computed quantities, or custom state) inside the dialog or grid rows.

In dialogs I like to use HTML field. Gives you complete freedom
