Hello,
i want to create a new tree in product.template wich will contain a field with type many2one from hr.employee
so when i just put the field into product.template.common.form it's work without any probleme
but when put the field in the new tree it seems work but when i want to make a test it doesnt work and it cant save and show this error message :
The operation could not be completed, probably as a result of:
- Deletion: you try to delete a record to which other records refer
- Creation / modification: a required field is not correctly filled
i have joined 4 pictures of what i have already done :
Based on this informations it is difficult to help you. Please post the code you have created for the new tree view. I recommend to create a module for a complete new tree view.
