Having persist without calling "on create"

I have a line that adds to a variable when a object is created. These objects have the persist behavior as I can goto a "store" layout at anytime. When going back to the layout the objects are in, it again adds them to the count. How do i circumvent this

Exe. I have 8 objects so (count = 8) I goto "store" layout and then come back. There are still 8 objects but count is now 16

You're probably creating them on start of layout. The old ones persist, and new ones are created. Add an additional condition or use a different condition.

without seeing your events you could have a global variable called "transition", set it to true when you are transitioning back out of your store, and add transition!=true condition to your original events.
