Description

Setting a PropertiesConfiguration autoSave=true via a ConfigurationFactory can
cause the underlying properties file to be completely overwritten.

Example:

config.xml:
<?xml version="1.0" encoding="ISO-8859-1" ?>
<configuration>
<properties fileName="application.properties" />
<properties fileName="ui.properties" autoSave="true"/>
</configuration>

application.properties:
application.name=Test App
application.version = 0.01
application.title = ${application.name} V${application.version}

ui.properties:
ui.test="stuff here"

Execute the code:
ConfigurationFactory factory = new ConfigurationFactory();
URL configURL = getClass().getResource("/config.xml");
factory.setConfigurationURL(configURL);
try

{ config = factory.getConfiguration(); System.out.println(config.getString("application.title")); System.out.println(config.getString("ui.test")); config.setProperty("ui.test", "will this get saved ?"); System.out.println(config.getString("ui.test")); }

catch (ConfigurationException e)

{ e.printStackTrace(); }

Program output:
12/04/2005 10:24:00
org.apache.commons.configuration.ConfigurationFactory$FileConfigurationFactory
createObject
INFO: Trying to load configuration application.properties

will this get saved ?

After execution
---------------
application.properties:
application.name=Test App
application.version = 0.01
application.title = ${application.name} V${application.version}

ui.properties:
