javascript - Polymer: Correctly remove polymer element whith elements inside it - Stack Overflow

I have a polymer element which has a costum element inside it. I want to remove everything (parent and child) when I click on it.

The problem is that every time I close an instance of the parent element I get an error. I think it's related to the fact I'm removing an element that has an element inside.

How can I remove it correctly?

Here's the method code:

closeWindow: function (event, detail, sender) {
    this.firstChild.remove();
    this.remove();
}

Here's the error I'm having:

Uncaught TypeError: Cannot read property 'length' of undefined

Here's an image of the error:

• Can you create a jsfiddle that shows off this behavior? – Peter Burns Commented May 17, 2014 at 23:36
• What's wrong with just this.remove()? – ebidel Commented May 19, 2014 at 23:00

This issue was fixed a few releases ago and should also work fine in Polymer 0.3.x onwards. If you run into any further issues with this.remove() within the scope of an element, please file an issue.

On polymer 1.5.0+ you do event.target.remove()
