NPE error

[mrosenfeld]

Hello,

I am experiencing a Null Pointer Exception Error in a flow and I do not know the reason. The complete stack trace is this:

java.lang.NullPointerException

Hi,


    ActivityImpl activity = (ActivityImpl) execution.getActivity();
    if (activity.isScope()) {

it seems that activity is null. Can you create jUnit test please?
