I'm creating a nattable with Filter, Groupby, Sorting feature, I'm applying the regular expression filter to a particular column. And I'm mass updating the properties for the same filter applied column. I'm getting error about 50% of the columns and remaining column is getting updated with new values.
Refer the code and error below
