Text - Dynamic Fields

[fabbaum]

If I want to output dynamic fields in the text, the values are output as 0.

In the Docker log, ‘Argument “” isn't numeric in subtraction (-) at input text line 1. ’ is output.

The error message occurs with this part of the code:

        # collect text to print
        my @TextData;

        if ( $Self->{Config}{Text} ) {
            for my $TextLine ( $Self->{Config}{Text}->@* ) {

                push @TextData, $LayoutObject->Output(
                    Template => $TextLine,
                    Data     => \%ReadableConfigItemData,
                );
            }
        }

Presumably because the hyphen is handled as a subtraction in the Hardware-SerialNumber string.

Hi @fabbaum ,

you're completely correct - the issue is that the rendering engine, Template::Toolkit, interprets the hyphen as substraction. We are aware of it, but currently, you will need a workaround.

In the system configuration entry, you may put something like this:

S/N: [% DFName = "DynamicField_Hardware-SerialNumber" %][% Data.$DFName %]

I hope this helps. I will update the issue when we fix the problem.

Kind regards,
Stefan
