Answer 1

It seem it was my misunderstanding of the terms and capabilities of the validations.
#NotNull and #Email are indeed both working but not as i imagined.
#NotNull is for validating Null not empty and that was my misunderstanding and similarly #Email cant do the validation on empty strings.
well thanks to everyone that reads this and i hope this can help someone. it might be too noob but its good to learn.
