ListGrid

[snjy85]

Hello all
I am using Smart GWT 2.2 version on ecllipse 3.4 ganymade.
I am creating a Grid by using ListGrid of smart GWT.Now in this grid has three overloaded methods for set data.Which are as follows :

1.setData(ListGridRecord[] data)
2.setData(Record[] data)
3.serData(RecordList data)

Now by using first way it is working properly.But when I tried third way it is giving me a class cast exception.
Exception as below :

17:56:26.054 [ERROR] [nextenders] Uncaught exception escaped
java.lang.ClassCastException: com.smartgwt.client.data.Record cannot be cast to com.smartgwt.client.widgets.grid.ListGridRecord
