Hello, when I use the following BeanClass and xhtml page, Datatable is not
populated with data, despite the method getAll() returns ResultSet that
contains customer names.
Code line System.out.println(crs.getString("Name")) iterates through the
ResultSet and prints customer names from customer table before the ResultSet is
being returned to h:dataTable component. This is what I get in Tomcat log:

This is the ManagedBean:
package com.corejsf;
import java.sql.Connection;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
import javax.annotation.Resource;
import javax.faces.bean.*;
import javax.sql.DataSource;
import javax.sql.rowset.CachedRowSet;
@ManagedBean
@RequestScoped
public class CustomerBean {
@Resource(name="jdbc/Sufa") private DataSource ds;
public ResultSet getAll() throws SQLException {
Connection conn = ds.getConnection();
try {
Statement stmt = conn.createStatement();
ResultSet result = stmt.executeQuery("SELECT * FROM customers");
CachedRowSet crs = new com.sun.rowset.CachedRowSetImpl();
crs.populate(result);
System.out.println("Start of Debug");
while(crs.next()) {
System.out.println(crs.getString("Name"));
}
System.out.println("End of Debug");
return crs;
} finally {
conn.close();
}
}
}
This is xhtml page:

<h:form>
<h:dataTable value="#{customerBean.all}" var="customer">
<h:column>
<f:facet name="header">#{msgs.nameHeader}</f:facet>
#{customer.Name}
</h:column>
</h:dataTable>
</h:form>
</h:body>
</html>
It's important to mention that the same code works perfect when I change JSF
implementation to mojarra-2.1.7.
It's seems like a bug.
Thanks a lot
