    Process in Eclipse Designer with two Script Tasks

    Kai Gebhardt Newbie

      Hi,

      I tried to create a process in the eclipse designer. I created a global process variable 'anzahl' as Integer. Then I created two script tasks. The first set 'anzahl' as 20. The second print the value of 'anzahl'.

      But the result is 'null' and not '20' as I expected. Here is my XML Code of process:

      Have I made some mistakes?

       

      Thanks a lot!
