Hi Bob,
Below is a part of my "HomePage.java". Should I not be using
"setStateful(true)" in my "HomePage.java"?
...
public class HomePage extends BorderPage implements Serializable {
public Form form1 = new Form();
public Table table1 = new Table();
private TextField searchField;
private Select typeSelect;
private PageSizeSelect pageSizeSelect;
public String title = "MyApp: Home";
// constructor
public HomePage() {
setStateful(true);
...
Thanks for your help,
Paul
