@Retention(CLASS) @Target({FIELD})

public @interface Length

Requires the component value to have at least min characters. The processor wires this into the Validator returned by Binding#getValidator() as a com.codename1.ui.validation.LengthConstraint(min, message).

@Bindable
public class SignupModel {
    @Bind(name="passwordField") @Length(min = 8)
    private String password;
}

Methods

`public abstract int min()`	Minimum number of characters.
`public abstract` `String message() default ""`	Override the default error message (`"Input must be at least <min> characters"`).

message

Override the default error message ("Input must be at least <min> characters").
