I don't have a test case or error messages, this is a general question. I'm using the PHP libraries and Oracle backend, current versions of datatables and editor.
Scenario is a very simple form where the user selects an identifier ("catalog-number") from a left-joined table. There is a second column in the left-joined table ("description") that I would like to use to populate a "placeholder" editor field when the form is in 'Create' mode, once the user selects the 'catalog-number'. The user then codes some additional fields that are saved to the database.
When the form is opened in 'Edit' mode, that value "description" is already populated via the join, but when the form is in 'Create' mode, it doesn't have the key for the left-join table reference yet, until the user sets the 'catalog-number'.
I am wondering if there is some way to use dependent to set a non-database field in the editor form to the "description" data when it is opened in 'Create' mode, based on the 'catalog-number' selected value. I don't want to edit this field or save it back to the database, I only want to display it to the user (in the editor form) while they are entering new records.
