Hello, I'm using gxt 2.2.5 and gwt 2.5.0, and I have a problem with ModelData. Here is example. I have grid and columnConfig. So:

column.setRenderer(new GridCellRenderer() {              @Override             public Text render(ModelData model, String property, ColumnData config, int rowIndex, int colIndex, ListStore listStore, Grid grid) {                 List<AccountGroupDto> accountGroups  = model.get(property);                 // some stuff here                  return groupsText;             }         });
when I try to do something with my list emenetns, I get some kind of type casting error. I used a debugger and it appears that type of my list elements is
and it can't be cast to
, which it should be. This error appeared when i've upgraded from gwt 1.7 and from gxt 2.0.1
