  After moving to the new version of wijmo 5.20201.663 from 5.20193.637, columns that use DataMap feature cause this error when changing columns property:

  Uncaught TypeError: Cannot set property groups of # which has only a getter

  Here is an example application that reproduces the issue:

  Thanks!

  Hello Slav,

  Is there a specific reason that you are updating the width of the column manually? The resize handler will automatically resize the column so there is no need to manually update the column.

  Hello Ashwin!

  No, there is no specific reason for that. That is just an example and the line with changing the width can be commented out, but that doesn’t change anything.

  Thanks!

  Hi Slav,

  If we remove the resizedColumn handler, the issue do not occur. But, still this seems to be a bug. So I have forwarded this issue to the developers with internal tracking id 441821. I will update you once this issue is fixed.

  Hi Slav,

  The developers have said that you should not set the columns by using the columns property. This is what causing the issue. If setting the columns property worked, it is just a coincidence. Instead, you may use the FlexGridColumn component to add columns.

  I have attached the updated sample which does not have the issue.

  ~regards
