I use odoo 11 latest version in windows.

My custom qweb template generate a good html, but the pdf does'nt work.

Default pdf reports work.

My code:

<?xml version="1.0" encoding="utf-8"?>

<odoo>

<template id="sale.sale_proposition">

<t t-set="o" t-value="doc.with_context({'lang':doc.partner_id.lang})" />

<div class="page">

<div style="text-align:center;font-size:1.5em;font-weight:bold;font-style:italic">
