I know I can specify the default value for a field in a one2many widget with tree view customizing the create control like this
<control>
<create string="Add a red one"
context="{'default_color': 'red'}"
/>
<create string="Add a blue one"
context="{'default_color': 'blue'}"
/>
</control>Can I do the same using a value from a field in the "header", I tried this one but doesn't work<control>
<create string="Add one with color from an header field"
context="{'default_color': color_field}" /> </control>
