java.lang.NullPointerException fired after importing and activating a simple workflow in SAP B1

[duzgun]

Hello all,

I have workflow sample that I have created in "SAP Busines One Studio", exported as xbml, imported in SAP Business One using "Workflow manager". When I have activated it after it has been imported succesfully, I've got the following error in workflow engine log file. What can fire this error message? Is there anyone can give a hint to solve this issue?

Thanks
