This is how it should work.For example:
1 ------column1------------
2 ------column2------------
3 ------column3------------
4 ------Column4------------
etc..
I have made an automated action for this, but it does not work as intended:
The automated action refers to the model of the one2many field and is triggered when a record is created. The following Python code is executed:
for line in record.picking_id.move_line_ids_without_package: for rec in str(record.x_studio_position): record['x_studio_position'] = len(record.picking_id.move_line_ids_without_package)
What happens is the following for e.g. 4 columns
4 ------column1------------
4 ------column2------------
4------column3------------
4 ------column4------------
It will write the total number in each row instead of the current column number.
