Hi, Host html page has downloaded the FB sdk.
<div id="fb-root"></div> <script>(function(d, s, id) { var js, fjs = d.getElementsByTagName(s)[0]; if (d.getElementById(id)) return; js = d.createElement(s); js.id = id; js.src = "// connect.facebook.net/en_US/all.js#xfbml=1&appId=334275213333094"; fjs.parentNode.insertBefore(js, fjs); }(document, 'script', 'facebook-jssdk'));</script> Now, I am adding this comments plugin on UIbinder as follows add this namespace to uibinder xmlns:fb="http://ogp.me/ns/fb#" then add the comments plugin to uibinder <fb:comments href="http://example.com" num_posts="2" width="470"></fb:comments> When running the application in dev mode, it fails with exception Prefix "fb:" has unrecognized xmlns "http://ogp.me/ns/fb#" (bad import?): <fb:comments href='http://example.com' num_posts='2' width='470'> (:133) Any good solution for facebook integration.
