> Hello,
>
> A user posted an issue with the Converter's here:
> [https://stackoverflow.com/questions/58825333/facesconverter-is-null-jsf-2-3-cdi-2-0]
>
> I investigated the issue, and it is caused by the beanManger#getBeans inside
> the /org/apache/myfaces/cdi/util/CDIUtils.java file. The getBeans returns an
> empty set instead of the converter bean. It searches by class, but it should
> also check by type. Since it's an problem with MyFaces code, I thought I'd
> open an issue here.
>
> I've provided a patch (overloading the CDIUtil.java methods to accept a type)
> and sample app (borrowed from StackOverflow).
>
> I only modified the code to search by type (1) when using getBeans. Type is
> obtained from creating a TypeLiteral (2).
>
> Since Validators don't check by type as Converters, I can make another fix if
> you don't have any issues with this patch.
> Please let me know if you have questions or suggestions for the code.
