Wizard treeview field automatically updated


Scenario: When the user double-click/view the line record from Lines treeview and change Approved Quantity field.

Observation: The Approved Quantity field value which displayed in Lines treeview will not get updated according.

How can we update the tree view fields automatically on a wizard when user modifying the line record fields value?

Thank you.

You can not wizard never save any thing automatically in the database.
It is the responsibility of the transition to store if needed the data from the view.
Also for Many2Many field, the wizard will only use the list of ids so you must use a One2Many field if you want to have the content.

But in general wizard are not the right tool to update stored records, you should directly edit the stored record in a form or use Model to collect the modification to apply to a record.
