Hi everyone, i'm an Odoo developer and i need your help in a question i'm facing today.

(i'm using odoo 16v on my enviroment)

So my task i to hide a span in a form view in 'sales' the snippet of the form is this:

<group name="sale_shipping">
   <label for="commitment_date" string="Delivery Date"/>
      <div name="commitment_date_div" class="o_row">
           <field name="commitment_date"/>
  <span name="expected_date_span" class="text-muted">Expected: 
	​	​<field name="expected_date" class="oe_inline" widget="date"/>
	​</span>
       </div>
</group>

i hided the field 'expected_date' correctly but the span's string "Expected:" still remain.

i tryed with this solution:

 <xpath expr="//group[@name='sale_shipping']/div[@name='commitment_date_div']/span[@name='expected_date_span']" position="attributes">
 <attribute name="invisible">1</attribute>
 </xpath>

but nevertheless, it give me this error along the terminal:

    raise err from from_exception
ValueError: Impossibile localizzare l'elemento "<xpath expr="//group[@name=&#39;sale_shipping&#39;]/div[@name=&#39;commitment_date_div&#39;]/span[@name=&#39;expected_date_span&#39;]">" nella vista principale

translated in english in short "Impossible to find the element in the view". but i gave to him the whole path to the span, i can find the solution.

someone can help me?

Thanks Cristian
