null object when using $ selector of node inside dom-if #667

Closed terrywarwar closed 8 years ago

terrywarwar commented 8 years ago

$['id1'] returns null when inside dom-if template. Works fine when it's outside the dom-if.

<template is="dom-if" if="{{!isLogin}}">
   <div id="id1"></div>
</template>

That's "as designed". If you wrap your code with asnyc(...) to give Polymer time to stamp the template, it will work.

Tried async(()=>($['md'] as PaperDrawerPanel).togglePanel()); and still getting a null object.

Also when isLogin is false?

terrywarwar commented 8 years ago

It's set on ready() set("isLogin", false);

I am pretty sure this is working as intended. The $ map is only going to contain things that exist on initial render. You could try setting isLogin to false in its initializer but I am not sure if that would work either. You should be able to use $$('#md') instead which does an actual query for the element.
