After creating the first popup, store a reference to it somewhere, perhaps in a variable of your application class. If you need to keep track of multiple popups, store them in an array. But when you close the popups, you'll need to clear the reference (or remove the element from the array). Otherwise it will stay in memory even though you can't see it.

I understand that i have to create an array to get all properties, no problem with that.
But i'd would like to select the old element (we'll call it OE), and could change properties, i explain me :
I have a group component, with a textInput inside.
The text of this textinput is set in another component (call ATI).
I would like, when i click on the OE, i would like to change his value rewriting thanks to ATI
If anyone have a way to fix it
So, if someone have the same problem, i give the way to fit it :
The instanciate popup add must be link with event.currentTarget.
myObjectAddedThanksToAddPopUp = event.currentTarget as myObjectAddedThanksToAddPopUp;
