Hi @Aaditya J,

To make it easier for us to diagnose the issue, could you upload the model shown or a replication of this model for us to examine?

This is a bug in the State Pie chart. It has been fixed for 18.2.3.

To work around this for now, follow these steps:

  1. Install the template
  2. Open the Process Flow for the template
  3. Add an activity called Get StateNode:

  4. Delete the Set CurState activity
  5. Change the Set Utilization activity:

  6. Change the Wait for Event activity. To listen to OnChange, use the sampler to sample a Tracked Variable in the Toolbox. Then replace the reference to the Tracked Variable with the correct code:

  7. Make sure the connectors are correct:


At this point, the chart should work. Here is a demo model you can reference.
