[jira] [Created] (BEANUTILS-526) copyProperty should instantiate
nested properties
Marco Janc created BEANUTILS-526:
------------------------------------
Summary: copyProperty should instantiate nested properties
Key: BEANUTILS-526
URL: https://issues.apache.org/jira/browse/BEANUTILS-526
Project: Commons BeanUtils
Issue Type: Bug
Components: Bean / Property Utils
Affects Versions: 1.9.4
Reporter: Marco Janc
The function _BeanUtils.copyProperty(bean, name, value)_ shall instantiate nested properties before copying them.
*Example:*
{code:java}
{code}
*class Foo*
*{*
*Bar bar;*
*}*
*class Bar*
*{*
*int id;*
*}*
We now have an instance of _Foo_ where _bar_ property is null and call:
{code:java}
Foo foo = new Foo();
BeanUtils.copyProperty(foo, "bar.id", 3);
{code}
This will throw an exception currently.
*Workaround*
In my generic copy method, i instantiate all required nested properties before.
