I’ve got Form domain class and there is typeOfTransaction property. This property is required

  • 0

I’ve got Form domain class and there is typeOfTransaction property. This property is required (blank: false). I want to write custom error message for this property, if the user does not set the value, the message must be appeared. 

com.example.domain.form.typeOfTransaction.blank = Type of transaction required

Above is the message, but I don’t get it when I’m trying to save form with empty typeOfTransaction field. Instead of this message I’ve got default message

"Please select an item in the list."

p.s. I don’t know where this default message is defined.

    If you use the absolute name of your class you need to use the exact name of the class, including capitalization – so I’m guessing you should put:

        com.example.domain.Form.typeOfTransaction.blank = Type of transaction required

    If you don’t use the absolute name you don’t capitalize the class name:

        form.typeOfTransaction.blank = Type of transaction required
