Portal Fiori Framework Page - IDLE Time Out - WDA Event

Hi gurus,

I have implemented the idle Time Out Portal following the following blog:

Portal User Idle time out - NW Portal 7.4:

In my case I use the Fiori Framework page and I need to set the Time out only in one page that contain a WDA.

After one minute the logout alert is showed correctly and the user is logged out from portal.

The problem is that the javascript don't receipt the event from WDA application.

Like open a try or click a button, and application show always the timeout alert.

There is a way to capture the wda event?

This is my code

Thanks in advances,

Massimo
