YUI 3 Tabview: SCRIPT5007: Unable to get value of the property 'setAttrs': object is null or undefined

Hi Mike,

 YUI().use('tabview', function(Y) {
//what ever you execute here take some time (since yui take some time to load)
})

tabview (which is your global variable) will be initialized only after YUI is loaded and initialized. all the code where you are using this tabview should stay with in YUI.use boundary.

Thanks Singh-Markandey. I changed tabview into a local variable, and that seems to have fixed the problem. I'm not sure why though, since I wasn't actually referencing the tabview variable anywhere outside the YUI.use boundary.

I changed the code to:

YUI().use('tabview', function(Y) {
var kyedtabs = document.getElementById('kyedtabs');
var tabview = new Y.TabView({srcNode:kyedtabs});
tabview.render();
});
