viewportZoom: Cannot read property 'css' of undefined

[sfranzyshen]

I'm trying to implement viewportZoom. I'm using the example give on the wiki ... but i get the error ... Uncaught TypeError: Cannot read property 'css' of undefined at Object.viewportZoom here is the code where it's being setup ... in my module.js file

{type:'wrapper', id:'wpr_viewport', version:'row', flex:'h', 
    arrive:function(){LCARS.helper.viewportZoom(this.dom, {width:1440, height:1080}); 
        window.addEventListener("resize", function(){LCARS.helper.viewportZoom(this.dom, {width:1440, height:1080});});},

    children:[

and the line(s) in the sdk ...

        viewportZoom:function(object, oArgs){
.......
            object.css('zoom', zoomLevel);

the error(s) only occur during the resize eventListener call ... it works fine when called from the arrive call ... seems this.dom behaves differently depending on who calls it ... a promise or event ...

Ah, looks like a 'this' issue since the call is within a parent function. It has to be set via variable instead.

I've updated the wiki to account for it.

        arrive:function(){
            var dom = this.dom;
            LCARS.helper.viewportZoom(dom, {width:1440, height:1080});
            window.addEventListener("resize", function(){
                LCARS.helper.viewportZoom(dom, {width:1440, height:1080}); 
            });
        }
