We need more code to see what happens there.
You have events that might have not set a var? There is something to
dig into your event order, or item initialization.

Hello all,
can anybody throw any pointer on this?
I have a tilelist (vertical/single column) with custom item renderer,

sometimes i get the following error (note: SOMETIMES once every ... do
not know 5 times):
TypeError: Error #1009: Cannot access a property or method of a null
object reference.
