Hi karthik,

First of all thanks for reporting this issue.

We will investigate this issue and will come back to you once we have any updates and information about reasons and fix estimations.

However I'd want to notice that currently Visualforce editor don't have it's own autocompletion that's familiar with apex components - in general it is HTML editor which has it's own code completion (closing tags, html elements, css elements, etc.) and code formatting.

We have plans for Visualforce-specific editor with code completion and other great features but I'm not sure when exactly we'll work on it.

Thanks,

Vladimir
