Hi at all,

I have a running odoo 8.0 system. At one Sales Order I get the following Error. 

 File "/usr/lib/python2.7/dist-packages/openerp/models.py", line 5320, in ensure_one
    raise except_orm("ValueError", "Expected singleton: %s" % self)
QWebException: "ValueError
Expected singleton: account.invoice.tax(728, 727)" while evaluating
"translate_doc(doc_id, doc_model, 'partner_id.lang', 'account.report_invoice_document')"

I tried to reproduce it but without success, neither I found a solution. 

Does anyone has an idea, how I can solve this and print the Invoice PDF?

Hello 

you have to add loop on the account_invoice_tax. 

you are getting multiple records instead on single record. that's why this  Expected Singleton error you are getting.

for ex:    <t t-foreach="line.tax_id" t-as="tax_id">
              <span t-field="tax_id.name"/>
           </t>

Hi Mitul, 

thanks for your fast reply. It seems as this should be the solution. But where do I find "account_invoice_tax" to change it? Is it a report or a model or something else?

into report you can from where error is comes. like into sale order you are made changes and print. at that time you got the error like expected singleton. so check the sale order lines tax value is print on report or not? if print then also check how you print the value or amount on report. ?

Your workaround helped a lot. Our salesman did the wrong tax entry. The Qweb report couldn't manage two entries and throwed the error. After changing this everything worked as it should.

Thanks for your help!
