[kune-commits] [Kune - Support #522] Gadgets stopped working

Fri Mar 15 18:19:14 CET 2013

Issue #522 has been updated by Christopher Baldwin.

Whoops - here's a better link:
http://live.brizmun.org:8888/#!sandbox.docs.29.11

Did some more digging to try understand what it's doing.  For some reason, gadgets.rpc._getTargetWin() is returning an iframe rather than a window object.  Everything else (message, target origin) seems to match.

<pre>
/* h = "wgadget_iframe_0" */

/* returns an iframe object, where .postMessage is useless */
i = gadgets.rpc._getTargetWin(h);
i.postMessage('{"not","a","real"}', 'http://message.net'');   // postMessage is not a valid function

/* returns a window object, where .postMessage is valid */
i = window.frames[h];
i.postMessage('{"not","a","real"}', 'http://message.net'');   // postMessage is a valid function
</pre>

Hi all,

I'm hoping that you can see something blatantly obvious that I've done wrong or missed.

Had Gadgets working in kune_0.2.0+b34_all.deb, after compiling and packaging kune_0.3.0+b23_all.deb from trunk, they all fail.

Did a clean install and clean database, nothing changed.

Google chrome's console shows that it's not able to talk to the cross-domain frame of the widget:
<pre>
  JS Error - Uncaught TypeError: Object #<HTMLIFrameElement> has no method 'postMessage' [wave-rpc.js:601]
</pre>

Firefox does the same thing:
<pre>
Error: TypeError: i.postMessage is not a function
Source File: http://live.brizmun.org:8888/others/splash/js/wave-rpc.js
Line: 601
</pre>

I'm not sure what else to check - comparing against what's served by kune.cc, I can't spot the difference.

Any ideas?
