[jira] [Updated] (CONFIGURATION-452) HierarchicalConfiguration with
XPathExpressionEngine does not work when setting a new property
[ https://issues.apache.org/jira/browse/CONFIGURATION-452?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Fabien Nisol updated CONFIGURATION-452:
---------------------------------------
Description:
The following code does not work as expected
{code:title=Bug.java|borderStyle=solid}
public class Bug {
public static void main(String[] args) {
try {
XMLConfiguration config = new XMLConfiguration();
// works
config.setProperty("test.property[@attribute]", "value");
config.setExpressionEngine(new XPathExpressionEngine());
// works
config.setProperty("test/property[@attribute]", "value");
// does not work
config.setProperty("test/property/@attribute2", "value2");
config.save(System.out);
} catch (ConfigurationException e) {
// @FIXME Traitement d'exception par defaut
throw new RuntimeException(e);
}
}
}
{code}
hangs with the following exception:
Exception in thread "main" java.lang.IllegalArgumentException: prepareAdd: Passed in key must contain a whitespace!
at org.apache.commons.configuration.tree.xpath.XPathExpressionEngine.prepareAdd(XPathExpressionEngine.java:223)
at org.apache.commons.configuration.HierarchicalConfiguration.addPropertyDirect(HierarchicalConfiguration.java:371)
at org.apache.commons.configuration.AbstractHierarchicalFileConfiguration.addPropertyDirect(AbstractHierarchicalFileConfiguration.java:140)
at org.apache.commons.configuration.HierarchicalConfiguration.setProperty(HierarchicalConfiguration.java:749)
at org.apache.commons.configuration.AbstractHierarchicalFileConfiguration.setProperty(AbstractHierarchicalFileConfiguration.java:158)
at Bug.main(Bug.java:29)
the setProperty() method does not work if the property have to be added. This behavior is not really wanted, because in some generic cases, we don't know if the property is set or not before trying to set it.
