View URL is not showing Navigation Bar

Hi Team,

Using Plugin i am updating View URL into attribute and using that attribute in Email template. 

But when i click it is redirecting to Respective entity view. But it is not showing Navigation Bar even though navbar is on.

http://<org URL>/_root/homepage.aspx?etc=4&viewid=%7B81484AGI-C21C-2121-Z40C-2Q1154FC1E5F%7D&viewtype=1039&navbar=on

Am i missing anything in URL?

var url = context.getClientUrl() +

"/main.aspx?etn=" + entityName + "&pagetype=entitylist&viewid=%7b" + viewId + "%7d&viewtype=1039&navbar=on";

window.open(url);

I put navbar=on still it is not working.

Looks like it is a bug.

Please help me on this.

Thanks,

Sreenath
