Just been trying out my new app in ie8 and it falls over and stops at the splash screen. The error is:
createView: function(viewId) {
var that = this;
var requirePath = this.convertViewIdToRequirePath(viewId);
return system.defer(function(dfd) {
system.acquire(requirePath).then(function(markup) {
var element = that.parseMarkup(markup);
element.setAttribute('data-view', viewId); <<<<< This is 54 and the line ie8 is complaining about.
dfd.resolve(element);
});
}).promise();
}
