I created the report, taking the following steps, as stated in the tutorial (I also created the module from the tutorial and there the report works):

- reports.xml in the data list

- added code in reports.xml:

<openerp>

    <data>

        <report

        id="report_idtest"        

        model="pprepair.ppmain"    

        string="Ppreport"

        report_type="qweb-pdf"

        name="pprepair.report_idtest_name"    

        />

        <template id="report_idtest_name">    

            <t t-call="report.html_container">

                <t t-foreach="docs" t-as="o">

                    <t t-call="report.external_layout">

                        <div class="page">

                            <h2>Report title</h2>

                        </div>

                 </t>

            </t>

         </t>

        </template>

    </data>

</openerp>

thats it. when I change the attribute "name" to the value of "pprepair.report_idtest_name", I get error with "QWebTemplateNotFound" and when I change it to the value ""pprepair.report_idtest" I get error with "IndexError".

I tried it on Odoo 9, because I read that it could be a bug and get the same behavior.

I may be overlooking a detail, this is driving me nuts.
