ListGrid Hover Customizer Problem with Non-String Columns

Using SmartClient Version: v9.0p_2013-07-05/Enterprise Deployment (built 2013-07-05) with IE9.

When you define a ListGrid hover customizer and have columns of non-string types you get a java script error:

06:48:32.630 [ERROR] [com.pci.ea.EA] Uncaught exception escaped

The problem is with passing the value of the column to your defined customizer in ListGrid.setHoverCustomizer - the code is:

if(fieldName!=null){
valueJ = this.getRawValue(record,fieldName);
}

when it should be:

if (fieldName != null) {
valueJ = $wnd.SmartGWT.convertToJavaType(
this.getRawValue(record, fieldName));
}

This worked when I override the setHoverCustomizer in my extension of the ListGrid object.
