Gaurav Gupta 8 Uncaught ReferenceError: Ext is not defined , Uncaught ReferenceError: chatter is not defined
I have used Chatter Feed component on my visualforce page . Example : The problem is that sometimes the chatter feed is loading and working completly fine while sometimes it shows the below JS error :
Uncaught ReferenceError: Ext is not defined
Uncaught ReferenceError: chatter is not defined
and therefore feed is loding but nothing in the feed is working properly like comment / Like / File etc.
I dont understand why it is happening sometimes and not everytime ... and how to get it resolved so that the problem never occurs.

If reRender is need from User perspective ,either use Oncomplete and restore all the bindings or every time reload the page .You will need to use inspect element and figure all the functions thats missing and use oncomplete and reload these functions .
