tableview navigation problem

Hi ALL,

Tableview navigation to newrow,nextpage buttons are not working .When i click on those buttons just page is refreshing but displaying same values instead of displaying next set of records.I am posting my code.Can anyone tell me where i am doing wrong?.Any help is highly appreciated.

JSP

<hbj:tableView

id="myTableView"

model="myBean.model"

design="ALTERNATING"

headerVisible="true"

footerVisible="true"

fillUpEmptyRows="false"

navigationMode="BYLINE"

headerText="ABSENCE OVERVIEW"

onNavigate="myOnNavigate"

visibleFirstRow="<%=myBean.getVisibleRow() %>"

visibleRowCount="10"

width="400 px" >

Bean

private String visibleRow ="1";

public void setVisibleRow(String visibleRow) {

this.visibleRow = visibleRow;

}

public String getVisibleRow() {

return this.visibleRow;

}

Dynpage

private int visibleRow=15;

public void onMyOnNavigate(Event event) throws PageException{

TableNavigationEvent tne = (TableNavigationEvent) event;

this.visibleRow = tne.getFirstVisibleRowAfter();

if(myBean!=null)

//myBean.setVisibleRow(new Integer(tne.getFirstVisibleRowAfter()+20).toString());

myBean.setVisibleRow(new Integer(tne.getFirstVisibleRowAfter()).toString());

if(myBean!=null)

myBean.setVisibleRowCount(new Integer(20).toString());

//String i = myBean.getvalue();

//response.write("this is the value"+i);

}

Thanks in advance
