setShowHover(true) is not working in latest build for listgrid.

Hi,
We have upgraded Smart Gwt-4.0p to Smart Gwt-4.1p(10 March 2015)
Browser : IE10, 11, Google Chrome: 43.0.2357.37 m.

I have updated SmartGWT library from night build 6/25/2015.

I am getting exception on ListGridField.setShowHover(true); in ISC_Core.js(line no: 285) file .
(TypeError: this.grid.frozenFields is null Stack from error.stack:)

Previous i was using SmartGWT library(8 MAR 2015 ). It was working fine .

I have attached sample code for your reference.

Please let me know for any clarification.

Thanks.
