Problem:
Adding a process instance duration report to a combined report crashes the combined report.
Steps to reproduce:
- Create a report with View: Process Instance, Measure: Duration (Avg), and Group By: None
- Save the report
- Create a new combined report
- Add the process instance duration to the combined report
Actual result :
Combined Report shows error message: "Cannot read property 'length' of undefined"
Expected result:
Combined Report shows a bar chart with the data of the process instance duration report
