Error with datasourcefield.setValidOperators() with some OperatorId's

[gvangass]

When I use the following OperatorId's I get errors:
DataSourceTextField description = new DataSourceTextField("description", "Description");
//description.setValidOperators(OperatorId.CONTAINS);
//description.setValidOperators(OperatorId.STARTS_WITH);
//description.setValidOperators(OperatorId.ENDS_WITH);

The following OperatorId's work:
//description.setValidOperators(OperatorId.ICONTAINS);
//description.setValidOperators(OperatorId.ISTARTS_WITH);
//description.setValidOperators(OperatorId.IENDS_WITH);

I did not check all the OperatorId's, there might be more that's not working.

I'm using SmartGWT 2.4
