jsf datatable select single row

In which radio button event should I put this ? I tried it on "onChange" and "onClick". didn't work.

Matara

not in onChange ,,, not in onClick
right click on the radio Button ,, then click event change listener, then the code window will open ,, then writhe that code

thanks for your reply.
I checked in both "Sun Java Studio Creator 2 Update 1" and "netbeans 6". But it doesn't show "event change listener" when rightclick on radiobutton. i've attched a screenshot. I'm using "Sun Java Studio Creator 2 Update 1" in my project. I'm using 2 datatables in the page.

Thanks

click ( Edit Event Handler ) then choose value changed listener then it will open the code window.

I'll only be able to try this on comming tuesday (05/02/2008) and let u know the resuls then.

Thank you

Hi,
I tried it. But it didn't work.
I think the problem is some where else.
I tried a new page putting two tables in a LayoutPanel. I put the following javascripts in two tables in the JSP (table names "matara" and "suresh").
function initAllRows() {
  var table = document.getElementById("form1:matara");
  table.initAllRows();
}

function initAllRows() {
  var table = document.getElementById("form1:suresh");
  table.initAllRows();
}

Then added,
selected="#{UserManager_1_1.selectedState}" in tableRowGroup tag
onClick="setTimeout('initAllRows()',0)" selectId="radioButton1"  in tableColumn tag
name="radioButton1" selected="#{UserManager_1_1.selected}" selectedValue="#{UserManager_1_1.selectedValue}" in radioGroup tag
for table matara and

selected="#{UserManager_1_1.selectedState1}"  in tableRowGroup tag
onClick="setTimeout('initAllRows1()',0)" selectId="radioButton2" in tableColumn tag
name="radioButton2" selected="#{UserManager_1_1.selected1}" selectedValue="#{UserManager_1_1.selectedValue1}" in radioGroup tag
for table surash

Then added the following codes in the bean.

    private TableSelectPhaseListener tableSelectPhaseListener = new TableSelectPhaseListener();
   
    public void setSelected(Object object) {
//        RowKey rowKey = (RowKey)getValue("#{currentRow.tableRow}");
//        if (rowKey != null) {
//            tableSelectPhaseListener.setSelected(rowKey, object);
//        }
    }
   
    public Object getSelected() {
//        RowKey rowKey = (RowKey)getValue("#{currentRow.tableRow}");
//        return tableSelectPhaseListener.getSelected(rowKey);
        return null;
    }  
   
    public Object getSelectedValue() {
//        RowKey rowKey = (RowKey)getValue("#{currentRow.tableRow}");
//        return (rowKey != null) ? rowKey.getRowId() : null;
        return null;
    }
   
    public boolean getSelectedState() {
//        RowKey rowKey = (RowKey)getValue("#{currentRow.tableRow}");
//        return tableSelectPhaseListener.isSelected(rowKey);
        return false;
    }
   
    private TableSelectPhaseListener tableSelectPhaseListener1 = new TableSelectPhaseListener();
   
    public void setSelected1(Object object) {
        RowKey rowKey = (RowKey)getValue("#{currentRow.tableRow}");
//        if (rowKey != null) {
//            tableSelectPhaseListener.setSelected(rowKey, object);
//        }
    }
   
    public Object getSelected1() {
//        RowKey rowKey = (RowKey)getValue("#{currentRow.tableRow}");
//        return tableSelectPhaseListener.getSelected(rowKey);
        return null;
    }  
   
    public Object getSelectedValue1() {
//        RowKey rowKey = (RowKey)getValue("#{currentRow.tableRow}");
//        return (rowKey != null) ? rowKey.getRowId() : null;
        return null;
    }
   
    public boolean getSelectedState1() {
//        RowKey rowKey = (RowKey)getValue("#{currentRow.tableRow}");
//        return tableSelectPhaseListener.isSelected(rowKey);
        return false;
    }

Then It works fine.

Then  I opened  the comments in first for methods and removed the unnecessary returns (i included when commenting the code).

Then it gives the error
"null" is null or not an object.  at the javascript line  table.initAllRows();

Then I changed second javascript function name to   table.initAllRows1();

Now it works fine. I used a message group to verify that the correct selected row id is returned for each table.

But I'm still not convinced about what's happening.
If possible help me to understand what's happening.

Thank you very much for your help.
