I tried to understand custom validators for forms.
So I thought about programming an own validator class by extending from AbstractValidator and store it in My/Package/Classes/Validators.
But how can I make this validator be available as My.Package.MyValidator in the form definition yaml file? The regular flow validators are availbe starting with “Neos.Flow:”. But I didn’t get the custom validator to work. It is not available. I defined an own preset in the settings.yaml. And then…what is missing?
Neos: Form: presets: mypreset: parentPreset: default
