Buttons are not loaded in list grid, when we do refersh

Hi,

We are using Smart Gwt-4.1p (23rd May 2014)
Browser: IE10, 11, Google Chrome:37.0.2062.124 m

Issue : Buttons are not loaded in list grid, when record is more than 30.
First time button is loaded properly.
Steps:
1. Expand column width so that will get horizontal scroll and last 3 button columns should display on scroll.
2. Click on refresh button

All the button is not loaded and user is not able to scroll till last width. Horizontal Scroll is coming back to beginning and button object is getting created on horizontal scroll.
Finally button is not displaying in list grid.

PFA files.
Thanks...
