hello , is there any hint why im getting this error ? maybe php version or what ? thanks for anyhelp 🙇♂️
there should be a check there to ensure $items is not empty before looping
I'm getting a warning before redirection when $items array is empty https://github.com/silverstripe/silverstripe-framework/blob/4b5d2c3cc292a690b5de9c5dec6ac9afe52abe69/src/ORM/UnsavedRelationList.php#L158
It may include some of the stuff you are looking for?
I think I remember seeing something similar in github
There may be other URL's, but I don't know them 😕
and there seem to be often forgotten or overlooked handy mechanisms like the collapsible composite field, nested tab sets and others
