Goal

The side navigation style in Open UI has a performance issue.

What we see is that every navigation between views with list applets, event listeners are being added on the window object.

Step to reproduce:

1. Place a debugger statement (in the file jsTreeCtrl.js) as shown below. Make sure you refresh (and clear browser cache) your browser.

   a.prototype.BindEvents = function() {

        var k = this;

        $(window).resize(function() {

             if (k.TreeLoaded) {

                 debugger;

                 k.Refresh(true)

             }

        })

    })

2. Click on the collapse sidenavigation bar, you will reach the debugger statements for two times.
3. Navigate (for instance) 4 times between views with list applets.
4. Click on the collapse sidenavigation bar, you will reach the debugger statements for seven times
