Hi,, i have created reports for a module,, as per '' http://odoo.guide/multiple-report-layout-step-by-step/ '', and have added the code in the report_student.xml
<?xml version="1.0"?>
<openerp>
<data>
<report
id="action_report_student_subject"
string="Another Report"
model="student.sub"
report_type="qweb-pdf"
name="student.another_report"
file="student.another_report"
/>
</data>
</openerp>
before updating module it is working fine, but when i update module it is throwing an error as "Qweb templates are missing ",
