If you want to use a dynamic SelectOptionCollection as value-label pairs for select options in Neos 9, this will be broken.
// ...
properties {
options = Neos.Form.Builder:SelectOptionCollection {
items = ${q(site).children('[instanceof Some.Package:NewsletterCategory]')}
# we use the node identifier as value, we could use "name" or "label" instead for example
valuePropertyPath = 'identifier'
}
}
Root cause is the SelectOptionCollectionImplementation which tries to fetch value and label with ObjectAccess::getPropertyPath directly from the object, which is a node in this case.
In Neos <9 the Node object had all properties as members, but this has changed in Neos 9
