GXT Grids not working

[cherian]

I have this peculiar problem with the grids.The application fires and event and new grid object is created every time .
I clear the SimplePanel and then add the new grid object to the SimplePanel.

Now the problem is that the first time the event is fired the grid object is displayed along with columns and rows.
The next time when the event is fired the new grid object is added to this simple panel but only the columns are shown but the rows are not displayed even though there is data in the grid.
Below is the code sample

if(sdfe instanceof ProcessEventsReceivedEvent){
            ProcessEventsReceivedEvent pere = (ProcessEventsReceivedEvent)sdfe;
            ApplicationMasterDetails amd = pere.getAmd();
            ProcessEventGrid peg=DataAndComponentFactoryImpl.getInstance().getProcessEventGrid(amd);            
            clear();
            
            
            if(currentAmd!=null){
                if(currentAmd.getId()==amd.getId()){    
                    
                    
                    add(peg);                                        
              
              
    
                    
                    
                }
            }
            else{
                
                add(peg);
              
              
                
            }
            
            
            
            
            
            
            
            
        }

Thanks,

The Problem is probably that you are not sizing your grid. SimplePanel is a GWT container that does not size its children. Have you tried to manually set a size to your grid?

Have you verified that the rows exist for example with the help of chrome debugger or firebug?

Than you Sven. Sizing was the issue
