Hello all,
I've already posted an issue about this problem in the linkit forum, but since I am not sure what is the appropriate place, I am posting here as well.

I would like to report an issue using the current latest releases of
LinkIt(3.2) and Field Collection (beta8).

Problem details:
If I have a field collection field with "unlimited" cardinality, after adding a second instance ("Add another item"), Linkit does not work anymore, due to a strange javascript error.

As soon as I remove the second item from the field collection, the Linkit starts to work again.
The same problem occurs if I use nested field collections, with more than 2 items in the child collection.

Please let me know if you need more information, screenshot, etc.

I am attaching a related issue.
Regards,
Oleg
