NullPointerException at: ZUGFeRDExporter.PDFattachZugferdFile(this)

[mitchneu]

Hello, I copied the MustangWriter example form the project. I just changed the input and the output filename and the path to the files. When the program tries to attach the Zugferd file by calling .PDFattachZugferdFile(this), I get the following NullPointerException:

Exception in thread "main" java.lang.NullPointerException

A similar error occurred in january. I also tried to attach custom XML which works just fine.

hi, tweimer just submitted a patch for mustang 2 on https://github.com/ZUGFeRD/mustangproject/pull/204 does that help?

Seems to be the same NullPointerException as in #165
