[jira] [Commented] (CONFIGURATION-793) Error reading a list of complex objects from JSON after 2.3

["Gary D. Gregory (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CONFIGURATION-793?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17576215#comment-17576215 ] 

Gary D. Gregory commented on CONFIGURATION-793:
-----------------------------------------------

In git master, I see that {{testGetList_nested_with_list}} passes and {{testGetList}} fails, nothing jumps out looking at the test in the debugger. Not sure why there is not a case for that.

I added {{testGetList_nested_with_list}} to the test class and a new disabled test method.

Thoughts from anyone?

Note: You assert parameters are reversed, and the pattern is {{assertX(expected, actual)}}.

>             Project: Commons Configuration
>          Issue Type: Bug
>    Affects Versions: 2.3

> 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.)
> https://issues.apache.org/jira/browse/CONFIGURATION-686 appears to have fixed access to lists of complex objects using the dot notation for strings (see testGetProperty_dictionaryInList() in TestJSONConfiguration) but has broken access to the list of complex objects.
