I use frozen columns in the listbox

[longtqdayma]

I use "frozen columns" in the listbox. On Zk6.5.4 OK. But I upgraded to ZK8.0.3 it encountered problems. When I scroll to the last and pulled back, the column disappeared.

<zk> <listbox id="tiendoListBox" vflex="1" hflex="1"> <auxhead> <auxheader label="Đơn vị" colspan="1" rowspan="2" /> <auxheader label="Chuyền" colspan="1" rowspan="2" /> <auxheader label="Đơn hàng"
