Daniel Atallah commented on BEANUTILS-465:
------------------------------------------
One solution may be to update the Introspection process so that these indexed
list properties instances of "IndexedPropertyDescriptor", then they could be
handled separately the way that arrays are.
Due to type erasure you'd have to assume a desired type of Object and the
conversion magic won't work at all.
There really isn't any way around that I can think of, but that isn't really a
problem because it's always worked that way.
> Indexed List Setters no longer work
> -----------------------------------

> Key: BEANUTILS-465
> URL: https://issues.apache.org/jira/browse/BEANUTILS-465
> Project: Commons BeanUtils
> Issue Type: Bug
> Components: ConvertUtils & Converters
> Affects Versions: 1.9.2
> Reporter: Daniel Atallah
> Attachments: BeanUtilsTest.java
>
>
> 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:
> http://commons.apache.org/proper/commons-beanutils/javadocs/v1.9.2/apidocs/org/apache/commons/beanutils/package-summary.html
> " 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.
