Report in PDF of iReport does not display the fields in the Summary band

[guiih_nastrini]

In the management system I'm working on, I generate a non-fiscal thermal printer voucher in PDF made in iReport using the PHPJasperXML library. In this voucher, when I have only one product (one row) in the Detail band, the Summary band fields are blank. When I have two or more products (two rows or more) in the Detail band, the fields are filled normally. In the iReport preview it works perfectly, with one, two or more products.

You can see below the jrxml code (only the detail and summary band):

The results in PDF:

1 - With one product (one row in the detail band):

2 - With two products (two rows in the detail band):

The values are already ready from the MySQL database, nothing is changed or incremented within the Summary. I already tried with parameter and variable but it did not work.

Does anyone have any ideas? Would it be a problem in the report or some server configuration?

Thanks in advance!
