I ran into a bit of an issue today while trying to render multiple instances of a component on a single page. Each component had a file input that was bound with an onChange event. When triggered the onChange function referenced the first component placed on the page no matter which instance was clicked.
The issue ended up being that the id of the input fields coincidentally overlapped. This meant that there were multiple instances of the field on the page with the same id value. Ensuring that each one was unique resolved the issue.
Took a fair while to narrow this one down so hopefully it’ll be able to help someone else!
