Hi,

Is it possible to have a change script on the “props.instances” on a flex-repeater, and use this to identify which instance[?] that fired an event?

Pass in a unique value like Index or ID to each instance. Use that to identity it.

Flex repeater children will also automatically be sent an `index` parameter - just have a named input parameter `index` on your view, and it’ll automatically be supplied an index by the flex repeater:
