Gxt Rpc Grid called to client and used as local grid - grid

Question

I have an ArrayList in my server I want to display it in a grid at client side. I am using RPC Mechanism for this purpose. The RPC call was successful but while am adding pagination it did not work. If have not done this in a proper way please guide me to do this correctly.
I just took the ArrayList to client and then added to grid. I thought that this is causing problems .
Here is my code:
ArrayList valls=new ArrayList();
public ContentPanel mainPanel1 = new ContentPanel();
public PagingToolBar toolBar = new PagingToolBar(10);
public ContentPanel cpc=new ContentPanel();
public ContentPanel mainPanel = new ContentPanel();
public ContentPanel cp = new ContentPanel();
public ListStore<BeanModelType> clientList=new ListStore<BeanModelType>();
public ListStore<BeanModelType> createGrid()
{
System.out.print("METHOD DDDDDDDDD");
final FeedServiceAsync feedService =Registry.get(RSSReaderConstants.FEED_SERVICE);
feedService.createNewFeed(new AsyncCallback<Feed>() {
#Override
public void onFailure(Throwable caught)
{
// TODO Auto-generated method stub
Info.display("RSSReader", "Unable to create a new feed");
System.out.print("ERRORRRRRR");
}
#Override
public void onSuccess(Feed result)
{
ArrayList valls=result.getVal();
PagingModelMemoryProxy proxy = new PagingModelMemoryProxy(TestData.getClients(result.getVal()));
PagingLoader loader = new BasePagingLoader(proxy);
loader.setRemoteSort(true);
/*
final PagingToolBar toolBar = new PagingToolBar(5);
toolBar.bind(loader);
loader.load(0, 5);
*/
clientList.add(TestData.getClients(valls));
/*
* if we remove the above code only shows the pagination not the content value
*
* Actual code shoiuld be like this
*
*
*clientList= new ListStore<BeanModelType>(loader);
*
* returns clientList;
*
*
* but int his method its not working sirrrr aM SORRY TO SAY THIS
*
*
*/
clientList = new ListStore<BeanModelType>(loader);
toolBar.bind(loader);
loader.load(0, 10);
loader.setRemoteSort(true);
}
});
return clientList;
}

List<ColumnConfig> configs = new ArrayList<ColumnConfig>();
ColumnConfig column = new ColumnConfig();
column.setId("name");
column.setHeader("CLIENT");
column.setWidth(200);
configs.add(column);
column = new ColumnConfig("name1", "CAMPAIGN", 150);
column.setAlignment(HorizontalAlignment.LEFT);
configs.add(column);
column = new ColumnConfig("name2", "SITE", 100);
column.setAlignment(HorizontalAlignment.LEFT);
configs.add(column);

configs.add(column);

Grid<BeanModelType> grid = new Grid<BeanModelType>(createGrid(), cm);
grid.setStyleAttribute("borderTop", "none");
grid.setAutoExpandColumn("name");
grid.setAutoExpandColumn("name1");
grid.setAutoExpandColumn("name2");
grid.setAutoExpandColumn("name3");
grid.setAutoExpandColumn("name4");
grid.setBorders(true);
grid.setStripeRows(true);
//grid.getView().setAutoFill(true);
//grid.setAutoWidth(true);
cp.setBodyBorder(false);
cp.setHeading("Employee List");
cp.setButtonAlign(HorizontalAlignment.CENTER);
cp.setSize(1440,609);
cp.setFrame(true);
cp.setAnimCollapse(false);
cp.setLayout(new FillLayout(Orientation.VERTICAL));
cp.setBottomComponent(toolBar);
cp.add(grid);
cp.setSize("", "370");
mainPanel.add(cp);

You cant do that. feedService.createNewFeed is Async process. What you had return on createGrid method is an empty clientList. reconfigure the grid inside onSuccess method
public void onSuccess(Feed result){
....
clientList = new ListStore<BeanModelType>(loader);
toolBar.bind(loader);
loader.setRemoteSort(true);
grid.reconfigure(clientList, grid.getColumnModel());
}
