> Click on root queue will show the complete applications
> But click on the leaf queue is not filtering the application related to the 
> the clicked queue.
> The regular expression seems to be wrong 
> {code}
> q = '^' + q.substr(q.lastIndexOf(':') + 2) + '$';",
> {code}
> For example
> 1. Suppose  queue name is  b
> them the above expression will try to substr at index 1 
> q.lastIndexOf(':')  = -1
> -1+2= 1
> which is wrong. its should look at the 0 index.
> 2. if queue name is ab.x
>     then it will parse it to .x 
>     but it should be x
