Re: Runtime error when switching a GWT Polymer Elements project from 2.8.0-beta1 to 2.8.0-rc1/rc2

You must be using Polymer.importHref() right ? and then you call  Polymer.ready() I had the same issue before, and I ended up removing Polymer.importHref() and Polymer.ready(), and adding the imports manually in the head, now it works fine. You can check out this commit in my project here: https://github.com/gwidgets/gwt-polymer-starter-kit/commit/7ce3c9523e3e7955f87659f9fcc4d03ac8928a5e 

If it does not work then you can open an issue, but you should now that the project's contributors are very slow to respond...

Yes I'm using the latest gwt-polymer-elements version, so 1.2.3.0, and it works for me with beta1.

The runtime error occurs also in production mode, not only in Dev mode.

I don't call whenPolymerLoaded() directly in my code, I only use Polymer.ready(Element e, Function f) but I guess whenPolymerLoaded() is then called within the Vaadin implementation. 

Actually I just would like to know if it's a gwt-polymer-elements 1.2.3.0 issue (in this case I will wait Vaadin to deliver the next release that will work GWT 2.8.0) or if it's a GWT issue that needs to be fixed before 2.8.0 is out.

Should I rather open an issue on the gwt-polymer-elements github project?

Normally, the latest version gwt-polymer-elements 1.2.3.0 is not supposed to work with beta1 but with SNAPSHOT or rc1, which version are you using? 

Another advise is try not use whenPolymerLoaded() in Dev mode, comment it out and take out the statements inside it, use it only when deploying to a server.

Hi,

I have a GWT Polymer Elements project that compiles and run ok with GWT 2.8.0-beta1.

When switching to 2.8.0-rc1 or 2.8.0-rc2, it compiles ok but doesn't run due to the follow runtime error:

Uncaught TypeError: ok_0_g$.call_1_g$ is not a function    Polymer.java:159

The Polymer.java:159 line is underlined in the code below:

    private static native void whenPolymerLoaded(Function ok)
    /*-{
        function done() {
          // Set our static reference to Base
          @com.vaadin.polymer.Polymer::Polymer = $wnd.Polymer;
          @com.vaadin.polymer.Polymer::Base = $wnd.Polymer.Base;
          // Polymer dynamic loaded does not remove unresolved
          $doc.body.removeAttribute('unresolved');
          //
          ok.@com.vaadin.polymer.elemental.Function::call(*)();
        }
        if (!$wnd.Polymer) {
            var l = $doc.createElement('link');
            l.rel = 'import';
            l.href = @com.vaadin.polymer.Polymer::absoluteHref(*)('polymer');
            l.onload = done;
            $doc.head.appendChild(l);
        } else {
           done();
        }
    }-*/;

I don't know if this is a GWT issue or a GWT Polymer Elements issue.

Any idea?

Thanks.
