Do this:
public class TableForm {
private List<SelectItem> tables = null;
private String selectedTable = null;
public String getSelectedTable() {
return selectedTable;
}
public void setSelectedTable(String selectedTable) {
this.selectedTable = selectedTable;
}
public List<SelectItem> getTables() {
if(tables == null){
tables = new ArrayList<SelectItem>();
tables.add(new SelectItem("1", "Table 1"));
tables.add(new SelectItem("2", "Table 2"));
}
return tables;
}
public String pagetoDisplay() {
if (selectedTable.equals("1")) {
System.out.println("Inside 1");
return "displaytable1";
}
else if (selectedTable.equals("2")) {
return "displaytable2";
}
else return null;
}
}
and the jsp:
<h:selectOneMenu required="true" value=#{tableform.selectedTable}>
<f:selectItems value="#{tableform.tables}"/>
</h:selectOneMenu>
<h:commandButton value="Submit" action="#{tableform.pagetoDisplay }"/>
This should work now,
cheers,
Gerald

Removed that. Changed the JSP selectOneMenu to the following:
<h:selectOneMenu value="1">
Also tried with:
<h:selectOneMenu value=" tableform.selectedTable">
Modified the getSelectedItem to as follows:
public SelectItem getSelectedTable() {
selectedTable = new SelectItem("1", "Table 1");
return selectedTable;
}

I have declared this as a SelectItem, any reason why that should not work?

Yes, I figured that, when one wasn't working I tried the other and forgot to
change it back. I have changed it back to
use getValue instead of getLabel.

Still getting the null pointer exception in the getPagetoDisplay method :(
Thanks for trying to help.
