The error itself is generic and more details would be needed to look into this.  If you are able to reproduce this in a sample I recommend starting a new thread with the sample and details on how to reproduce the issue.  If you are unable to reproduce the issue in a sample, you can use the developer tools in your browser to see what causes the error.  Knowing the line of code that causes the error or the call stack might help to give hints on how to resolve it.  Also you could look at the network activity to see if there are any scripts that aren't being correctly loaded.

Hi Jeevamani, Can you share the solution you found for this problem. I am facing the exact same thing. Thanks.

Jeevamani - it would have been so much more productive if you had actually shared that answer instead of just saying, "I found My Answer". You've effectively left your fellow developers in the lurch with this non-answer.

Thank You For Your reply....I found My Answer
