Retaining BSP Page values with Javascript popup window

Question

Hi Experts
We are using a customized BSP application for our performance
Management. To propmt users for saving their appraisal documents
before a session timeout,we used an Javascript popup message(alert
window). This window doesnot affect the BSP page in any way.(code
provided below)
Per changed requirement,we now have to retain the BSP page values once
the user clicks 'OK' on this javascript popup window. I used the page
refresh option with script. But this is erasing the earlier values.
Can anyone tell me,how i can holdback the BSP page values after the
user action on the popup window. If a piece of code is provided,it
would be greatly appreciated.
Thanks in Advance
Alan

Answer 1

If the BSP page is refrehed, all the user input it sent back to the server. If you don't do anything special, the input is lost and not sent back to the client again. You can go to your controller class' DO_HANDLE_DATA to read the user input, and store it in the controller class to send it back to the client.
If you don't use controller classes, the equivalent would be onInputProcessing. A more advanced alternative would be to use MVC model binding, which would do most of the stuff automatically for you.
