Issue

If variables are changed in a sub process, the "Call a Sub Workflow" step in the parent breaks. The variable becomes blank under the "Start Sub Workflow" section of the step and cannot be deleted:

The workflow will still deploy, however when an instance is started it will hang on the call sub workflow step.

Symptoms

A blank variable field in the "Start Sub Workflow" section of a sub workflow call step will appear and cannot be deleted. This will cause an error when the workflow is deployed and an instance hits the Call Sub Workflow step.

Troubleshooting Steps

A fix is scheduled for this issue in K2 5.2. In the meantime, you can workaround this issue by recreating the step in the parent process.
