AttachHeader DetachHeader with filters and column insertion/

Hi, I am adding and removing columns to my grid at runtime, and it doesn’t seem to work that well with filters. What I do is increase the number of columns, then remove the old header (for the filters, which is located at index 1), and attach the new header. However, when I type into these new filter boxes, it doesn’t seem to work correctly. It gives the following message:

_cellType is null or not an object

Line 867

Char 30

Please provide us any kind of example where we can reproduce this issue.

After I posted, I noticed this post: … n%20filter

Is that still accurate?  Do newly inserted columns not work with filters?
