Deployment error when using Custom Voting Rule

Issue

When using the "# of responses" option in a Custom Voting rule on a Task step, deployment fails with the error: 

Missing reference at ConfiguredVotingCustomRule 'ConfiguredVotingCustomRule' in Event 'Task' in Activity 'Task'. Error: Value cannot be null. Parameter name: count. ..etc

Closing and re-opening the workflow, the "# of responses" box is cleared out.

Error Code

Resolution

1. Create the custom voting rule

   

2. Select the radio button for "First response"

   

3. Switch the radio button back to "Custom voting rule"

   

Deployment should now be possible with the voting rule intact.

Additional Information

This has been logged as a bug and will be fixed in a future version of K2.
