Polymer iron-media-query not working as previous versions -

-

the following component used work in 0.5, doesn't work in 1.0. if uncomment h1 tag display values returned iron-media-query, output ",,"; meaning of course values blank.

<dom-module id="app-image">     <!-- should select correct image based on size -->     <style>         :host {             display: inline-block;             position: relative;             overflow: hidden;         }         :host > ::content img { display: block; }     </style>     <template>         <iron-media-query query="(min-width: 422px)"                           querymatches="{{ issmall }}"></iron-media-query>         <iron-media-query query="(min-width: 642px)"                           querymatches="{{ ismedium }}"></iron-media-query>         <iron-media-query query="(min-width: 1202px)"                           querymatches="{{ islarge }}"></iron-media-query>         <!--             note: following see actual values             specific variables. unfortunately, it's plain blank :(              <h1><span>{{ issmall }}</span>, <span>{{ ismedium }}</span>, <span>{{ islarge }}</span></h1>         -->          <template is="dom-if" if="{{ !issmall }}">             <content select="[tiny]"></content>         </template>          <template is="dom-if" if="{{ issmall && !ismedium }}">             <content select="[small]"></content>         </template>          <template is="dom-if" if="{{ ismedium && !islarge }}">             <content select="[medium]"></content>         </template>          <template is="dom-if" if="{{ islarge }}">             <content select="[large]"></content>         </template>     </template> </dom-module> <script>     polymer({         is: "app-image",         ready: function() {             console.log(this.issmall);             console.log(this.ismedium);             console.log(this.islarge);         }     }); </script>

the 3 console.log statements return undefined, when i'm expecting boolean values. leads me believe iron-media-query element doesn't update property.

should iron-media-query used differently it's previous incarnation, core-media-query? documentation correct?

ta,

rewrite querymatches query-matches.
