Missing detail arrow icons when refresh!

[omega]

Hello,

I'm using Paramquery Pro version.

Grid's detail arrow icons are missing when i want to refresh with new data. Why could it be?

I added jsfiddle link to below. Thank you.

detail is a special kind of column which can be only be declared once.

Other columns can be added, updated or removed from the colModel but the entire colModel can't be replaced in case of detail.

Thank you very much for your help, I also found out that I can use the destroy command to destroy the grid and then reload it.
