Perform the following local-change:

Java Source:

String portalName = tools.getParamValue("portalName");
ClipboardPage pg_decPage = tools.findPage("Declare_pyDisplay",true);
if(pg_decPage != null){
ClipboardProperty cp_pyDisplay = pg_decPage.getProperty("pyDisplay");

if(cp_pyDisplay != null ){

cp_pyDisplay.remove(portalName);

}
}

When condition: Param.portalName != ""

2. Call the activity during window unload using the following script:

function closeOpenItems(e){

  var safeURL = new SafeURL();
  var portalName = pega.u.d.portalName;
  if(portalName){
    safeURL.put("pyActivity","ClearDataModel");
    safeURL.put("portalName",portalName);
    pega.u.d.asyncRequest("POST", safeURL, null, null, {"bAsync":false});
  }

}

window.onbeforeunload = function (e) {
closeOpenItems(e);
}
