Grid refresh using server polling
posted

Hi,

 I m trying to refresh the contents of the grid by using the server polling mechanism.
 
I can call the server side getter for the list to be populated after the time interval.
The problem is with rendering the data on the web page.

Do i need to use grid.dataBind()? if yes, where?

Is there something i m missing? or is it that this feature is not supported yet.

Code is given below:

JSP:

<f:view>
 <html>
 <head>
 <script type="text/javascript">
 var t;
 function walker()
 {
  ig.smartSubmit('eventform:events',null,null, 'eventform:events', null);
  t=setTimeout("walker()", 10000);
 }
 </script>
 </head>
 <body onload="walker();">

 <h:form id="eventform">
  <ig:gridView dataSource="#{notification.eventlist}" id="events" binding="#{notification.grid}">
   <ig:column>
    <f:facet name="header">
     <h:outputLabel id="listheader" value="Event ID" />
    </f:facet>
    <h:outputText id="eventid" value="#{DATA_ROW.eventid}" />
   </ig:column>
   <ig:column>
    <f:facet name="header">
     <h:outputLabel id="listheader" value="Event Description" />
    </f:facet>
    <h:outputText id="eventdesc" value="#{DATA_ROW.eventDesc}" />
   </ig:column>
  </ig:gridView>
 </h:form>
 </body>
 </html>
</f:view>

BEAN:

public class NotificationBean implements Serializable {
 
 NotificationService notificationService = new NotificationService();

 private List eventlist;
 
 private GridView grid;

 public List getEventlist() {
  eventlist = notificationService.getAllEventsAsList();
  return eventlist;
 }

 public void setEventlist(List eventlist) {
  this.eventlist = eventlist;
 }
 
 public GridView getGrid() {
  return grid;
 }

 public void setGrid(GridView grid) {
  this.grid = grid;
 }
}

Thanks,
Sachin.
