Hello,
All macros are fully tested and working. We have tested the Generate PDF A-1.txt macro included in phpdocx 10 and it's working correctly.
What OS are you using? How have you added the macro? Please note that as explained in the documentation, the macros included in the package must be added to the Module1.xba file of the user that runs LibreOffice, not using the LibreOffice GUI.
The following line is correct and valid in the Module1.xba:
oPropertyValue.Name = "Hidden"
If you are opening LibreOffice to add the macro using the GUI, then you may need to add:
oPropertyValue.Name = "Hidden"
Regards.
