pxSessionTimer logoff timer does not display countdown window



Post upgrade from Pega 6.3 SP1 to Pega 7.1.7, the pxSessionTimer does not display the pop-up countdown window. User launches CPM Portal and waits for time-out to occur, however the expected pop-up window does not appear. This functionality worked fine in Pega 6.3 SP1.

Error Messages

Not Applicable

Steps to Reproduce

Launch CPM Portal to observe that the time-out window does not display.

Root Cause

This is a known issue with logoff timer in Pega 7.1.7. This is scheduled to be resolved in Pega 7.1.8 but easy to implement in Pega 7.1.7 as well.


To use the Logoff Timer in Pega 7.1.7 follow the below steps:

1. Copy pxSessionTimer and rename to SessionTimer<ProjectName>.

2. Place the following script at the bottom of the existing <script> block just before the </script> tag.

function desktop_restartTimeoutWarningTimer(){
    if (pega.desktop.TimeoutTime && pega.desktop.TimeoutTime > 0) {
        var nTimeoutWarningTime= (pega.desktop.TimeoutTime - pega.desktop.TimeoutWarningWindow) * 60000;

        if (nTimeoutWarningTime >= 0) {
                pega.desktop.TimeoutWarningCountdown = self.setTimeout("desktop_showTimeoutLogoffDialogNew('"+pega.desktop.TimeoutWarningWindow+"')",nTimeoutWarningTime);

function desktop_showTimeoutLogoffDialogNew(strTime) {
    var iTime = parseInt(strTime);
    iTime = iTime * 60000;
    var oSafeURL = new SafeURL("@baseclass.ShowLogoffTimer");
    pega.openUrlInModal.showModalDialog(oSafeURL,iTime, 210, 620, function(ret){    
        if (ret == null || ret == "ok") {
        } else {
            pega.u.d.gDirtyOverride = false;
            try {
            } catch(e) {
                pega.u.d.replace('pyActivity=LogOff&pzPrimaryPageName=pyDisplayHarness', null);

3. Copy the activity ShowLogoffTimer into your application ruleset (into same ruleset where you put SessionTimer<ProjectName>).

4. Copy and rename LogoffTimer HTML rule to LogoffTimer<ProjectName> (Found in Step1 of ShowLogoffTimer)

<Title><pega:lookup property=".pyMessageLabel" value="Log off timeout warning" /> </Title>
<pega:include name="DesktopStyles" />
var iTime;

    function init() {
        window.returnValue = "ok";
        iTime = parseInt(window.dialogArguments);
        window.setTimeout("closeMe()", iTime);    
    function closeMe() {
        if(typeof window.closeModal == 'function') { window.closeModal(); } else { window.close(); }

    function setTime() {
        var numSec = iTime / 1000;        

        var min = Math.floor(numSec / 60);
        var sec = numSec % 60

        if (sec <= 9) {
            sec = "0" + sec;

        if (document.all){
            document.all('_minutes').innerText = min;
            document.all('_seconds').innerText = sec;
            document.all('_minutes').textContent= min;
            document.all('_seconds').textContent= sec;

        iTime = iTime - 1000;

5. In Step1 of ShowLogoffTimer use LogoffTimer<ProjectName> HTML rule.

Placement of SessionTimer in Pega 7.1.7

If you need the new SessionTimer in the portal header, the section needs to be placed at bottom of the portal header. Drag and drop a section from "Layout" in design view and select your SessionTimer<ProjectName>. Configure parameters as required.
