4.1.3.2 Properties The current value identified by the value property is normally of type DataModel. However, a DataModel wrapper instance must automatically be provided by the JSF implementation if the current value is of one of the following types: java.util.List Array of java.util.Object java.sql.ResultSet (which therefore also supports javax.sql.RowSet) javax.servlet.jsp.jstl.sql.Result Any other Java object is wrapped by a DataModel instance with a single row. Convenience implementations of DataModel are provided in the javax.faces.model package for each of the above (see Section 4.2.1.4 "Concrete Implementations"), and must be used by the UIData component to create the required DataModel wrapper.
4.2.1.4 Concrete Implementations The JSF implementation the javax.faces.model ArrayDataModel ListDataModel ResultDataModel javax.servlet. tag library) ResultSetDataModel therefore means ScalarDataModel data set. Note that there is no SetDataModel available. However, you could write your own. On 12/5/05, Martin Marinschek <[EMAIL PROTECTED]> wrote: > P.S.
