Hey,

Following up from https://community.palantir.com/t/how-can-i-reference-the-index-of-my-sub-container-in-a-slate-repeating-container/447 I was able to correctly fetch the index of my sub-container.

What is the correct way to fetch the elements from the array returned by f_function_1?

Slate uses handlebar.js for value injection. The correct syntax for looking up and index in an array based on another variable is to use the helper function lookup. Thus, the correct syntax is:

{{ lookup f_function_1 w_container_2.index }}
