Hey,
I'm new to JBPM and tried to make a Workitem where I upload a PDF as byte and then fill the Formfields with the parameters given by the process. I managed to upload the PDF as byte in BP. Then I tried to use PdfBox as recommended to me and put in my pom like this:
After I upload the workitem in BP to try to create the task in the BPMN Modeler i get several NullPointerExceptions similar to this:
When I go to the Dependecy section in my Project it seems that everything was found though.
I would be very thankfull if anyone knows what the Problem is.
Thanks,
Duc
