Hello,

i am trying to link a custom paper format to an inherited report via xml code (in Odoo 10 community), but i am getting following error when updating my module mit -u my_module_name when starting the server.

Error:

ParseError: "null value in column "name" violates not-null constraint
DETAIL:  Failing row contains (635, 1, null, 1, 2017-04-11 08:06:45.853033, null, 2017-04-11 08:06:45.853033, ir.actions.report.xml, null, null, t, pdf, null, null, null, null, null, t, null, f, null, null, null, f, null, 15, null).
" while parsing /home/odoo/customaddons/my_module/views/paperformat.xml:27, near

<record id="sale.report_saleorder_document" model="ir.actions.report.xml">
    <field name="paperformat_id" ref="my_module.paperformat_sale_order"/>
</record>

and this is the code for my paper format:

<record id="paperformat_sale_order" model="report.paperformat">

            <field name="name">Papier Angebot / Auftragsbestätigung / Rechnung</field>

            <field name="default" eval="True"/>

            <field name="format">custom</field>

            <field name="page_height">297</field>

            <field name="page_width">210</field>

            <field name="orientation">Portrait</field>

            <field name="margin_top">45</field>

            <field name="margin_bottom">25</field>

            <field name="margin_left">20</field>

            <field name="margin_right">20</field>

            <field name="header_line" eval="False"/>

            <field name="header_spacing">30</field>

            <field name="dpi">90</field>

        </record>

and this is how i linked the paperformat to the sale order report:

<record id="sale.report_saleorder_document" model="ir.actions.report.xml">
    <field name="paperformat_id" ref="my_module.paperformat_sale_order"/>
</record>

I just can't see what i did wrong here.

Any help would be greatly appreciated :)
