Trigger validation when a nested form changes

[zoltanhalasz]

Question
I have a formly form that uses a 2 date pickers and a 2 custom types ( FieldType). How can I trigger the validation on the outer form when the value of the custom type (which is a form itself) is changed?

I tried with hooks, onInit within the customtype, on field level, using valueChanges and it doesn't work...

A stack blitz would be really helpful to see exactly what issue you are having .

Better define validation in the parent control which will trigger validation when one of the field is changed.
