Oliver Heger resolved CONFIGURATION-224.
----------------------------------------
Fix Version/s: Nightly Builds
Resolution: Fixed
A comment describing the behavior of getProperty() was added to the
Configuration interface. So I am closing this ticket now. The problems with
ConfigurationDynaBean are now dealt with in ticket CONFIGURATION-227.
> BaseConfiguration.getProperty() returns reference to intenal store collection
> object instead of a clone

> Key: CONFIGURATION-224
> URL: http://issues.apache.org/jira/browse/CONFIGURATION-224
> Project: Commons Configuration
> Issue Type: Bug
> Environment: 1.3RC2
> Reporter: Gabriele Garuglieri
> Priority: Minor
> Fix For: Nightly Builds

> Attachments: list.patch
>
>
> When the property object is a List or an Array,
> BaseConfiguration.getProperty() returns a reference to the object contained
> in the store.
> This means that changing that object, changes the content of the properties
> store without an explicit setProperty() or addProperty().
> Also any change to the object in the store will change the object that the
> code has reference to, but the user is not aware that the property has
> changed unless he has added a ConfigurationListener.
> Attached a patch to make the object returned by
> BaseConfiguration.getProperty() a clone of store content, to avoid side
> effects when changing Collection properties.
