Actually now that I look the snippet I wrote was wrong. I have my indices
starting at 0 and go to 2.
The block if index == 2 executes and I still can't access
application.com3mgetData() unless there is a delay involved.
How would the creation policy effect this?

Viewstack’s children index is zero based, so you need to start at zero and go
to two

I hope this helps!

Check the viewstack creationPolicy property :)
