  Hi,
  
  We are sorry but we are unable to replicate the issue at our end.
  
  We created a sheet with the same code as in snippet provided and the sheet was working as expected. Please have a look at the sample and let us know if we are missing something to replicate the issue or provide a small sample to help in the further investigation:-
  
  https://stackblitz.com/edit/js-9uaweq?file=index.js

  Also please provide info about the framework, Wijmo build number, browser and OS you are getting the error on, so that we may test on a similar configuration.
