Cliff Evans updated CONFIGURATION-793:
--------------------------------------
Description:
We have just attempted to move from version 2.2 to 2.7 and have encountered and
issue whilst attempting to read a List from a JSON formatted configuration file.
The issue appears to have been introduced in 2.3.
Adding the following tests to
org.apache.commons.configuration2.TestJSONConfiguration will demonstrate the
change. These tests will pass against 2.2 but fail agains 2.3 (and 2.7.)
{noformat}
@Test
public void testGetList_nested_with_list()
{
assertEquals(Arrays.asList("col1", "col2"),
jsonConfiguration.getList(String.class, "key4.key5"));
}
@Test
public void testGetList() {
final List<Map> configList = jsonConfiguration.getList(Map.class,
"capitals");
assertEquals(configList.size(), 2);
assertEquals(configList.get(0).get("country"), "USA");
assertEquals(configList.get(0).get("capital"), "Washington");
assertEquals(configList.get(1).get("country"), "UK");
assertEquals(configList.get(1).get("capital"), "London");
}
