[bv-dev] Feedback for BVAL-214

[Hendrik Ebbers]

How should we handle the proposals?

- discuss by mail?
- PR to: https://github.com/beanvalidation/beanvalidation.org/blob/staging/proposals/BVAL-214.md
- comment on page: http://beanvalidation.org/proposals/BVAL-214/

Currently I have no idea what is the right way :)

Cheers,

Hendrik

> 
> BeanValidator<ContactDataModel> contactValidator = BeanValidator.build(ContactDataModel.class);
> contactValidator.withProperty("city", () -> cityField.getText()).
>         withProperty("zipCode", () -> zipCodeField.getText());
> 
> In addition I think that it will be important to have a better feedback for the violations that are based on a UI field. If you have a violation based in the text of the cityField you normally want to mark that field in the UI. I think a consumer can really help here:
> 
> contactValidator.withProperty("city", () -> cityField.getText(), v -> markCityField(v));
> By doing so you will always get the set of violations that is based on the value in the city field.

> You can find a first idea of such an interface and 2 view controller examples here: https://github.com/guigarage/validation-playground/tree/master/src/main/java/com/guigarage/dynamicvalidation <https://github.com/guigarage/validation-playground/tree/master/src/main/java/com/guigarage/dynamicvalidation>

>> As per [1] there is a BV 2.0 Hackergarten event scheduled for Tuesday the 20th, led by Michael Nascimento. Thanks for taking this initiative, Michael!
>> 
>> Interesting things to discuss and explore might be proposals written by then (e.g. the one around List<@Email>, Emmanuel is working on updating this one) and things like ordering of constraints (BVAL-248, [2]) or David Blevins' proposal around using Lambdas (BVAL-515, [3]). David should be there, so make sure to get hold of him :)
>> 
>> Another interesting topic is integration with other specs/techs (e.g. javax.money or JavaFX). Specifically, there are several pending issues around the integration of BV and JAX-RS:
>> 
>> * Provides means to disable BV during JAX-RS lifecycle validation (BVAL-520, [4])
>> * Provide facility for more flexible HTTP error codes when using BV with JAX-RS (BVAL-518, [5])
>> * Pass the request locale to BV's MessageInterpolator
>> 
>> Mostly these things would have to be done on the JAX-RS side, so it would be great to have a chat with them if there is the chance for it.
>> 
>> Apart from that, essentially anything would be great which helps with forming a picture of the community's needs and requirements.

>> Thoughts?
