We have :
- task.parent_ids(the project)
- task.partner_id (the customer)
- work.task_id
I want something like this in work.view.xml
<field name="task_id.partner_id" modifiers="{}"/>
<field name="task_id.parent_ids" modifiers="{}"/>
But he don't understand task_id.customer and task_id.parent_ids
How can i put this information in tree, calendar or form view ?
