Polymer Tutorial step 1 multiple core-select events

[timcash]

for step one of the polymer tutorial (http://www.polymer-project.org/docs/start/tutorial/step-1.html) when I click a tab I get two 'core-select' events and two console.log("Selected: " + tabs.selected); for each click.

"dependencies": {
"polymer": "Polymer/polymer#~0.3.3",
"core-elements": "Polymer/core-elements#~0.3.3",
"paper-elements": "Polymer/paper-elements#~0.3.3"
}

This is actually expected behavior. One of the events is coming from the deselected element and one is coming from the newly selected element. You can check the isSelected attribute of the event to determine the selected state of the dispatcher. We need to update this in the tutorial.

Well that makes sense =). Thanks for the fast reply!

cc @arthurevans can we update this bit of the tutorial? I was initially confused by it as well :D
