Passing arrays into attributes

[Filipe Araujo]

I was looking at core-selector and it allows for  ".selected = ['x','x'], however setting the attribute to a string of that value does not function the same way.Is that accidental,  or is this an intended restriction?  If accidental, is there a convention for attributes with array / object values?

Hi,

If a Polymer element hints that the type of a property is an array or an object, you can use JSON strings in the attribute value. Example here: http://jsbin.com/noxof/1/edit
