I got error when editing a new added item in binded table. Here the snippet http://webix.com/snippet/3724257f . Try to select one of the above item and then click the button to add item on the bottom table. Then double click the id to edit.
The error in console says “Uncaught TypeError: Cannot read property ‘depends’ of undefined”
found a solution with a tricky one http://webix.com/snippet/574568e8
where every add should register a new id. But this means adding id directly to the data.
id property is used to identify the record, so direct editing of id is not safe operation.
You can add an extra property, id of record which can be edited. So each record will have a true non-editable ID and some property which represents a visible ID, which can be changed.
