[java] Uncaught JavaScript exception [_3 is undefined] in

[vluison]

After smartgwt update, from 2.1 to 2.2, in my project if I attempt to grouping ListGrid by columnName the effect is:

[java] Uncaught JavaScript exception [_3 is undefined] in http://127.0.0.1:8888/myproject/sc/modules/ISC_Grids.js, line 912
