Yep, that makes sense.Thanks about that!
Although I thought apply a method (global counter) which knows how many requests I need and then render the view only once I know all my requests have got an answer and I parsed what I need from each one, that is gonna avoid show a partial completed view when requests are still going on...(At least toggle a css class for display it only once is 100% built)
Anyway, thanks a lot for the answer as I didn't know the views where rendered partially!
