Hi Ross, - Hi, I'm using a OneToManyTypeConvertor to split a single input value - containing multiple MAC addresses separated by a comma separator into a list - of strings.I'd like to specify further validation rules on the format of - each MAC address. Is there a simple way to do this with the - OneToManyTypeConvertor? Can I specify an additional mask that applies to - each element?
As far as I can tell, you can't specify additional validations to each element of a value converted with OneToManyTypeConverter. In your case, one possible but somewhat clumsy solution is to validate the value with a mask, but here you are validating the entire input, including commas and spaces between values. For example, to validate a list of values are all uppercase letters: @Validate(converter=OneToManyTypeConverter.class, mask="([A-Z]+(, +)?)+") Like I said, it is not a pretty solution and if there is a validation error, you just get one message saying that the entire input is not valid; you won't be told which value in the list caused the error. - I know I can create a MAC address type and then create a type convertor but - I am wondering if there is a simpler way of doing this. That's a cleaner way of going about it, or you can just use Strings but create your type converter and a subclass of OneToManyTypeConverter that overrides the method: protected TypeConverter getSingleItemTypeConverter(Class targetType) in which you return your type converter. - Another example would - be where the user enters a list of numbers and you want to range check each - number entered. Certainly a valid feature, but again, as far as I can tell, you can't do this with OneToManyTypeConverter. E.g. this does not work: @Validate(converter=OneToManyTypeConverter.class, minvalue=1, maxvalue=5) public List<Integer> numbers; You *can* validate each number of the list: @Validate(minvalue=1, maxvalue=5) public List<Integer> numbers; but in this case each number has to be submitted separately instead of in a single String. Hope that helps.
