[SOLVED] JSF ExternalContext.redirect infinite loop on IE window.open

I am trying to redirect to xhtml pages using the p:treenode and having externalContext.redirect on onNodeSelect method, it works perfect in firefox and chrome but not on IE (versions 9, 11 and edge are the ones I tried).

On IE the page continuously redirects to the same page once I click on a tree node.

My application opens in window.open, when I use the direct url for my application in IE, I do not see this redirect looping issue, it only happens when I open my application in window.open that too only in IE.

Here is the window.open logic

<div class="floatLeft" style="padding: 0 5px; width: 75px;">
    <div class="autoCenter center">
        <a href="javascript:void(0)" onClick="launch('http://pc055265.my.search.app:8080/UpgradeParis/faces/login/ssologin.xhtml?app=IHW', 'PARIS-IHW')">
          <img id="j_idt18:2:j_idt20" src="/cta-landing/javax.faces.resource/paris_IHW_50x46.png.jsf?ln=images" alt="PARISIHW" title="PARIS - IHW" />
        </a> 
        PARIS-IHW
    </div>
 </div>

The launch javascript

<script type="text/javascript">
    var wnd
    function launch(url, app){
        if(!wnd || wnd.closed){
            wnd = window.open(url, app, 'height=700,width=1350,toolbar=no,location=no,menubar=no,status=no,titlebar=no,resizable=yes,scrollbars=yes');
        }
        wnd.focus();
        return false;
    }
</script>

my xhtml which prints my navigation

<p:tree id="navTree" name="navTree" value="#{navTree.root}" var="node" selectionMode="single" 
        selection="#{navTree.selectedNode}" >
        <p:treeNode expandedIcon="fa fa-folder-open" collapsedIcon="fa fa-folder" styleClass="navTree">
            <h:outputText value="#{node.name}" title="#{node.name}"/>
        </p:treeNode>
        <p:treeNode type="document" icon="fa fa-file-text-o fileColor" styleClass="navTree">
            <h:outputText value="#{node.name}" title="#{node.name}"/>
        </p:treeNode>
        <p:ajax event="select" listener="#{navTree.onNodeSelect}" />
</p:tree>

backing bean NavigationTree, the NavigationBean is just a pojo which has string attributes name and link. Added a debug statement inside onNodeSelect method, the control goes into the method only once

@Named("navTree")
@SessionScoped
public class NavigationTree implements Serializable {

private TreeNode root;
private TreeNode selectedNode;

@Inject
private NavigationService service;

@PostConstruct
public void init() {
    root = service.createParisTree();
}

public void setService(NavigationService service) {
    this.service = service;
}

public TreeNode getRoot() {
    return root;
}

public TreeNode getSelectedNode() {
    return selectedNode;
}

public void setSelectedNode(TreeNode selectedNode) {
    this.selectedNode = selectedNode;
}

public void onNodeSelect(NodeSelectEvent event) throws IOException{
    ExternalContext ec = FacesContext.getCurrentInstance().getExternalContext();
    StringBuffer url = new StringBuffer(ec.getRequestContextPath()+ "/");
    TreeNode currentNode = event.getTreeNode();
    NavigationBean node = (NavigationBean) currentNode.getData();

    if(node !=null){
        url.append(node.getLink());
    }else{
        url.append("faces/ui/home.xhtml");
    }

    ec.redirect(url.toString());

}
}

And NavigationService is where i build the navigation

public class NavigationService implements Serializable {

public TreeNode createParisTree() {
    TreeNode root = new DefaultTreeNode(new NavigationBean("Menu", "root"), null);
    TreeNode home = new DefaultTreeNode(new NavigationBean("Home", "faces/ui/home.xhtml"), root);
    TreeNode ihw = new DefaultTreeNode(new NavigationBean("IHW", "faces/ui/home.xhtml"), home);
    TreeNode nor = new DefaultTreeNode("document",new NavigationBean("RE Search", "faces/ui/ihw/common/facility-search.xhtml"), ihw);
    ...
}
}

This is from the logs where I print redirect along with the deltaspike windowContext.getCurrentWindowId(), I do not see any javascript errors in developer tools

Using Mojarra 2.2.12-jbossorg-2 with PrimeFaces 6.1, deltaspike 1.7.2, CDI 1.2, Windows 7 & 10, Internet Explorer 9, 11 and edge.

Any help is greatly appreciated.
