Click-event is lost after a while

Question

I have built an XPage with a click event for a button, that writes data in the session scope.

<xp:button value="all" id="button4">
    <xp:eventHandler event="onclick" submit="true"
        refreshMode="norefresh">
            <xp:this.action><![CDATA[#{javascript:sessionScope.selectedView = "view1";print("view1!");}]]></xp:this.action>
    </xp:eventHandler>
</xp:button>

After some clicks the print output "view1" is not displayed anymore. So the event somewhere has gone lost and I have no idea why this has happened.

Answer 1

It should not happen if you click continuously every eg 5 seconds, no matter how many clicks you made. Does it really happens that way?

If it stops working after some period of inactivity, check Application Timeout and Session Timeout properties of your application. When the session gets destroyed on time-out, all the views are also purged, so the engine does not have any target for your POST request anymore.

Increase the session and application timeouts, or much better use keepSessionAlive component that is the part of Extension Library
