Update form fields in UI in between an AJAX call

[mainak1990]

Hi,

I have a multi row selection datatable where there is column named "Status'. My objective is to update the status in between an Ajax call.
Suppose I have selected 5 rows and clicked on the command button then, once the status of the first row is received from data base it needs to shown to UI immediately and execution continues for the rest rows and update accordingly one by one in UI.

Currently I am able to update the status for all the rows after the entire list is populated in managed bean class. So the status of those rows are getting updated all together.

How can I achieve this? Please help me asap.

Thanks,

Probably you could use PUSH events to do so.
In the server, once a row is ready, you could push an event with a websocket connection to the browser, which is independent from the HTTP AJAX call, and on receiving the javascript event, update a single row with javascript.
You need to configure the Atmosphere framework with PrimeFaces, which is actually quite easy.

Hi Miguel,

Thanks for your input.

It was really something new interesting approach.

Just one thing can you give me some example of this or how to integrate Atmosphere Framework with PrimeFaces?

Thanks in advance.

just check the userguide and showcase. It's called PrimePush.

Or you could just do a poll to check the status of the row updates, and update them as needed.

I assume the row-by-row updates take considerable time?

My requirement is like that only. I need to update the rows one-by-one.

Anyways thanks everyone for your inputs. I will try this with PrimePush and get back to you.
