I have a ApplicationAlertsDao which is a managed bean and performs edit and savealerts

public class ApplicationAlertsDao {

private ArrayList<ApplicationInstanceTaskAlertBean> alerts;
Logger log;
private HtmlDataTable dataTable;
private ApplicationInstanceTaskAlertBean alert;

public ApplicationAlertsDao() {

}

public ArrayList<ApplicationInstanceTaskAlertBean> getOracleAlerts(){
return getAlerts("oracle");
}

public ArrayList<ApplicationInstanceTaskAlertBean> getMysqlAlerts(){
return getAlerts("mysql");
}


public ArrayList<ApplicationInstanceTaskAlertBean> getAlerts(String catName) {
System.out.println("loading alerts");
Connection con = null;
alerts = new ArrayList<ApplicationInstanceTaskAlertBean>();
try {
Context ctx = new InitialContext();
DataSource oracleds = (DataSource) ctx.lookup("java:jdbc/oracle/mgtdb");
con = oracleds.getConnection();
Statement st = con.createStatement();
ResultSet rs = st.executeQuery("select site_name,site_type ,server_type,app_inst_task_alert_message ,app_inst_task_alert_comments,app_inst_task_alert_time,seq_app_inst_task_alert from app_inst_task_alerts join app_inst_task_alert_comments using(seq_app_inst_task_alert)join app_inst_tasks using(seq_app_inst_task)join app_instances using(seq_app_instance)join servers using(seq_server)join applications using(seq_application)join app_categories using(seq_app_category)join sites using(seq_site) where app_category_name='" + catName + "'");
while (rs.next()) {
alert = new ApplicationInstanceTaskAlertBean();
System.out.println(rs.getString(1));
alert.setSiteName(rs.getString(1));
alert.setSiteType(rs.getString(2));
alert.setServerType(rs.getString(3));
alert.setAlertMessage(rs.getString(4));
alert.setComments(rs.getString(5));
alert.setAlertTime(rs.getDate(6));
alert.setAlertId(rs.getInt(7));
alerts.add(alert);

}

setAlerts(alerts);
} catch (NamingException ex) {
//java.util.logging.Logger.getLogger(ApplicationAlertsDAO.class.getName()).log(Level.SEVERE, null, ex);
} catch (SQLException ex) {
ex.printStackTrace();
} finally {
try {
con.close();
} catch (SQLException ex) {
ex.printStackTrace();
}
}
return alerts;
}


public void setAlerts(ArrayList<ApplicationInstanceTaskAlertBean> alerts) {
System.out.println("setting alerts");
this.alerts = alerts;
}

public HtmlDataTable getDataTable() {
System.out.println("getdatatable");
return dataTable;
}

public void setDataTable(HtmlDataTable dataTable) {
System.out.println("setdatatable");
this.dataTable = dataTable;
}

public ApplicationInstanceTaskAlertBean getAlert() {
return alert;
}

public void setAlert(ApplicationInstanceTaskAlertBean alert) {

System.out.println("setting alerts");
this.alert = alert;
}

public String editAlert(){
System.out.println("editAlert");
System.out.println("row index"+dataTable.getRowIndex());
//System.out.println((FacesContext.getCurrentInstance().getExternalContext().getRequestParameterMap().get("index")));
alert=(ApplicationInstanceTaskAlertBean)dataTable.getRowData();
System.out.println("return edit");
return "edit";

}

public String saveAlert() {
Connection con = null;
try {
InitialContext ctx = new InitialContext();
DataSource ds = (DataSource) ctx.lookup("java:jdbc/oracle/mgtdb");
con = ds.getConnection();
PreparedStatement st=null;
st = con.prepareStatement("update app_inst_task_alerts set app_inst_task_alert_message=? where seq_app_inst_task_alert=?");
st.setString(1,alert.getAlertMessage());
st.setInt(2,alert.getAlertId());
st.executeUpdate();
st=con.prepareStatement("update app_inst_task_alert_comments set app_inst_task_alert_comments=? where seq_app_inst_task_alert=?");
st.setString(1,alert.getComments());
st.setInt(2,alert.getAlertId());
st.executeUpdate();

} catch (Exception ex) {
ex.printStackTrace();
}finally{
try {
con.close();
} catch (SQLException ex) {
// java.util.logging.Logger.getLogger(ApplicationAlertsDAO.class.getName()).log(Level.SEVERE, null, ex);
}
}

return "save";
}

}

what i want to achieve is, i am displaying all the alerts thru dataTable and adding an edit button to each row. the selected row is displayed in another page in editable formate and save. i could perform the edit and save but the problem is, when i am using binding attribute in both the tab's datatable, only one tab is displaying the data. the other one is blank. if i doest add the binding attribute, i am not able to do selecte a row correctly and edit and save. How to solve this

I hope i am clear on what i want.Thanks for going thru my question.
Any advice would be helpful.... thanks in advance
