Magnolia CMS: Multivalue field containing a composite field issue

Question

I try to configure a dialog with a Multivalue field containing a composite field.

However, I get the following error:

Invocation of method buttonClick in info.magnolia.ui.form.field.MultiField$1 failed.

Answer 1

As pointed out in a similar question on Magnolia Forum, the issue was in the configuration tree.

I had 2 configuration nodes at an incorrect level of the dialog's tree.

It's pretty deep so one must watch out for misconfiguration.

Solution:

Dialog config tree exported
