Thank's Jojo for the reply
but the point is different, like I said this code work very well, I don't understand why, is not implemented in the new jem, take a look, this one open the add venue page inside a modal box and insert the new venue directly, so you can add the venue without exit from the add event page, very usefull ! (I putted the button inside the choosevenue modal so i can choose an existing venue or add a new venue).
My problem is that, after press the 'apply' button (save), I need to stay (or reload) for to complete the missing data and than 'save' and close with the save (save&close) button.
And NO, (I answer the easy question) I can't complete all in one step because at first I need to store the facebook ID for to import and load the data after the first save (apply).
For now I must reopen the edit venue page after saving all and it is a little tricky.
