How to create two respone for one request

Question

Hi
is there any way for us to create two response for one request
the scenario is as below
1. user click on update button for particular record in the datatable (
after its get updated and status get updated = 'UPDATED' it will remove the object from ObjectListDataProvider and clear the tablePhaseListener ).
2. After it gets updated successfuly , i want to prompt the user with generateExcel function which using response.getOutputStream() using Apache POI.
How can we combine 1 and 2 together
Here what i have tried and didnt work
1. i tried to put the generateExcel function in destroy() method after page is rendered but it gives me Exception
2. i tried to put the generateExcel function in prerender() method
but the page will only execute the generateExcel function
- the data still get updated to the database but it doesnt refresh the page ( i meant the removing object and tablephaseListener.clear() doesnt work )
3 . i tried to put generateExcel Function after it process the data
public String updateData()
       //update data
       if(success){
            // prompt user to save excell sheet
        return null;
     }This one also doesnt work and gives the same behaviour as number 2
The Prompt to save excel sheet still gets popped up
but the page just doesnt get refreshed
Thanks
is anybody know the workaround?

Answer 1

yea i did set some alert message and clear the table by calling
provider.removeRow and commitChanges
it just doesnt reflected in the page that we see
by actually is already removing the row from the provider
Thanks
