[tryton] get report from proteus

[Antonio Roncero]

Hi,

i want to write a report from proteus. I use the code below

    def download_invoice(invoice_id):
        report=Report('account.invoice')
        Invoice = Model.get('account.invoice')
        invoices = Invoice.find(condition=['id','=',invoice_id])
        type_, data, print_, name = report.execute(invoices, {})
        target = open(name+'.odt', 'w')
        newFileByteArray = bytearray(data)
        target.write(newFileByteArray)
        

The file 'Invoice - FV0005.odt' is created fine but is emty. What is the 
correct way to do it?

Thanks
