Can't export Kickstart project

[modsley]

Hello.
In eclipse I create Kickstart project, create Kickstart process diagram, put Review step on the diagram.

When I try to export project I get error
org.activiti.workflow.simple.exception.SimpleWorkflowException: Property reference: {{null}} does not reference an existing property.

Thank you.

In my case, this error had to do with the assignment of a human step being left blank. after assigning the assignee to a form property the export worked.
