Polymer 1.0 App-Drawer - Uncaught TypeError when n

Question

Displaying the menu only to members I've got this bit of code

<app-drawer-layout fullbleed>

  <!-- Drawer content -->
  <template is="dom-if" if="{{signedIn}}">
   <app-drawer>
   ....

This displays the menu only when users are logged in to the application. It works fine but is there anyway to remove the error it causes in the console.

error:

polymer-mini.html:2046 Uncaught TypeError: Cannot read property 'getWidth' of undefined

Answer 1

The layout logic in <app-drawer-layout> requires an <app-drawer> to determine the appropriate container margins. I don't see an option to disable that logic.

A workaround for the error you're seeing is to create an empty <app-drawer> by moving the dom-if inside the <app-drawer>:

<app-drawer>
  <template is="dom-if" if="{{signedIn}}">
    ...
  </template>
</app-drawer>

This unfortunately would create a blank drawer before the user signs in, but maybe this is acceptable for your app. codepen
