Affects Version/s: 6.1.1 CE GA2, 6.1.20 EE GA2
After upgrading to 6.1 it's not able to modify the workflow design for a workflow defined before the upgrade.
Steps to reproduce:
1- Startup 6.0.12 portal
2- Deploy kaleo web
3- Shutdown the portal
4- Upgrade to 6.1GA1 or 6.1GA2
5- Deploy kaleo web, kaleo forms and kaleo designer (and the new upgrade hook for kaleo if you needed)
6- Drag and drop the kaleo form in a page
7- Add a new process selecting single approver as workflow and Edit
You won't be able to see the workflow design and the attached exception is thrown "designing_workflow_exception.txt".
NOTE: You won't have any problem if you use kaleo for first time in 6.1
New definitions uploaded after the upgrade will work properly.
