Cannot read property 'addEventListener' of null

Hey there!

I’m having a issue with ember 2.7.0 and ember-power-select 1.0.0-beta.8.

trigger.js:43 Uncaught TypeError: Cannot read property 'addEventListener' of null

The stack trace points to https://github.com/cibernox/ember-power-select/blob/a6364c7fe1692817c4572e7623116757e470b170/addon/components/power-select-multiple/trigger.js#L46

With ember 2.6.1 this error does not happen.

Let me post some of my findings:

I had ember-power-select v1.0.0-beta.17 installed and ember-power-select-with-create v0.1.10, when I updated to ember-power-select-with-create v0.2.0 it started working.

Long version: I updated my package.json to reference the latest commit in Ember Power Select like this "ember-power-select": "git://github.com/cibernox/ember-power-select.git#b43879f13f0d2b3e19999ec5275f53c3b05ffcf0",

That didn’t work (I did delete node_modules and bower_components and reinstalled), one thing that I found odd was that while navigating through the source in my project I had the following code in trigger.js for power-select-multiple.

var optionsList = document.getElementById(this.elementId + '-ember-power-select-multiple-options');

But looking for this line of code in EPS source code, I could only find a reference to this.elementId in the changelog saying that it was removed. Which means that I was somehow using an “older” power-select?

That’s when I remembered to update power-select-with-create which now has on its own package.json version 1.0.0-beta.14, but previously (on 0.1.10 has version 0.10.X of EPS).

Hope it helps someone.

I’ll try to get a twiddle up in the next few days
