Hey Odoo devs,

I'm working on a POS customization in Odoo 18, using the latest OWL 2-powered frontend. I needed to add a simple disabled prop to the ActionpadWidget — nothing fancy — just to conditionally block the payment button for certain users.

So I did what seems obvious:

• Patched the component:

  
  patch(ActionpadWidget.prototype, {
      props: {
          ...ActionpadWidget.props,
          disabled: { type: Boolean, optional: true },
      },
  });
  

• Extended the template:

  <xpath expr="//ActionpadWidget" position="attributes">
      <attribute name="disabled">this.pos.user.pos_block_payment</attribute>
  </xpath>
  

And bam — Owl throws:

OwlError: Invalid props for component 'ActionpadWidget': unknown key 'disabled'

Apparently, the template gets validated before the patch is applied?
Is there a clean workaround I’m missing here?
