AdvanceCriteria of GWT is not finished, there is just one AdvanceCriteria constructor and no any other function provided.

If more funciton which is valid in SmartClient like, 'Or', 'And', 'Greater than', 'Less than' operator can be provided, it is much more convenient for development.

Without these function limit developer's usage on SmartGWT in database binding and operation.

Many Thanks
