Subject [jira] [Commented] (BEANUTILS-465) Indexed List Setters no longer work
Date Wed, 01 Oct 2014 20:24:34 GMT


Oliver Heger commented on BEANUTILS-465:

Do you have a proposal how to solve this problem?

The stricter validation performed by these converters is also enforced by the introduction
of generics; the old behavior is probably no longer possible because it would require returning
an object which is incompatible with the expected return type. One could even argue that the
old behavior was problematic because of this.

I guess the change in behavior is related to the issues BEANUTILS-445 and BEANUTILS-446.

>             Project: Commons BeanUtils
>          Issue Type: Bug
>          Components: ConvertUtils & Converters
>    Affects Versions: 1.9.2
>            Reporter: Daniel Atallah
>         Attachments:
> After upgrading to commons-beanutils 1.9.2 from 1.8.3, I ran into a bug where indexed
List setters no longer work.
> Per the documentation at:
> " As an extension to the JavaBeans specification, the BeanUtils package considers any
property whose underlying data type is java.util.List (or an implementation of List) to be
indexed as well."
> This no longer appears to be an accurate statement.
> The cause appears to be more strict validation in both org.apache.commons.beanutils.converters.StringConverter.convertToType()
and in org.apache.commons.beanutils.converters.AbstractConverter.
> There is now an explicit cast to the target type, which throws an Exception instead of
the previous behavior of simply returning the input value unconverted.
> I'll attach a test case that works with 1.8.3, but no longer works with 1.9.2.
