PropertiesConfiguration.save() doesn't persist properties added through a DataConfiguration
-------------------------------------------------------------------------------------------
Key: CONFIGURATION-332
URL:
https://issues.apache.org/jira/browse/CONFIGURATION-332 Project: Commons Configuration
Issue Type: Bug
Affects Versions: 1.5
Reporter: Emmanuel Bourg
Priority: Critical
Fix For: 1.6
There is a regression in Commons Configuration with PropertiesConfiguration wrapped into a DataConfiguration. The properties added through a DataConfiguration aren't persisted when the configuration is saved, but they can be queried normally. Commons Configuration 1.4 wasn't affected by this issue.
The following test fails on the last assertion :
{code}
public void testSaveWithDataConfiguration() throws ConfigurationException
{
File file = new File("target/testsave.properties");
if (file.exists()) {
assertTrue(file.delete());
}
PropertiesConfiguration config = new PropertiesConfiguration(file);
DataConfiguration dataConfig = new DataConfiguration(config);
dataConfig.setProperty("foo", "bar");
assertEquals("bar", config.getProperty("foo"));
config.save();
// reload the file
PropertiesConfiguration config2 = new PropertiesConfiguration(file);
assertFalse("empty configuration", config2.isEmpty());
}
{code}
