> when using Host Selector widget to select one host, like "localhost", in workspace.js
code save_host() function
>    for(var i=0;i< obj.options.length;i++) {
>         if(obj.options[i].selected) {
>             if(i!=0) {
>                 cookie = cookie + "," + obj.options[i].value;
>             } else {

>     var myAjax=new Ajax.Request(

> this code will rise a ajax request to set hosts in session, but the hosts variable in
session will be set like ",localhost", a additional comma will be added even there is only
one host selected. I think this bug is introduced by above code.
> And this will cause MetricsController.java getSeriesBySessionAttribute() function
>    String[] rkeys = (session.getAttribute(skey).toString()).split(",");
> to split this hosts variable to a zero length string, like string "" and  string "localhost",
using this string "" to get data in HBase which will retrieve no data.
