My error:
Invalid property 'salary' of bean class [net.lacit.militaryRegistr.entity.Spravochnik]: Bean property 'salary' is not readable or has an invalid getter method: Does the return type of the getter match the parameter type of the setter?
I understand that there is no explicit getter/setter for the salary field, but how to bind this form? thanks in advance!
