Can not create custom PDF in version 1.5.2

Support
1

Hi,
I was using my own templates for quotes and invoices with 1.4.10 which worked quite nice.
I understand that under the hood mpdf was updated from 6.1.0 to 7.x.

Now I fail to generate PDF quotes and invoices. If I use the default template, everything works fine.

I am usung Ubuntu 16.04, php7.0.15 and Apache.

I get the errors posted below.

Is there any recommendation to get more debug output?

Thanks a lot
Cornelius

Line 1806 in Tag.php is the table parser. So I commented out all tables.

Message: Undefined property:
stdClass::$quote_custom_bedarfsanfor

I realize, that the parser does not know the custom fields anymore. How are these used in the template, now?

This topic explains the change naming of the custom_fields:

I boiled it down, that it seems to be a problem with the item-table… :frowning:
Especially the footer where the voodoo with sun and the colspan occurs.

Oh bummer!

$show_discounts was renamed to $show_item_discounts. This is what caused the trouble.
After renaming it to $show_item_discounts in my template, everything works fine!
