Subject [jira] Commented: (CONFIGURATION-342) DatabaseConfiguration.copy() loses list/array values
Date Wed, 22 Oct 2008 15:43:44 GMT

    [ https://issues.apache.org/jira/browse/CONFIGURATION-342?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12641890#action_12641890

Scott Wells commented on CONFIGURATION-342:
-------------------------------------------

After a little more debugging, it looks like it may be worse than just copy.  I just tried
to add the list directly and it still only picked up the first element.  So basically the
following:

DatabaseConfiguration dc = new DatabaseConfiguration(...);
dc.addProperty("myList", Arrays.asList("1", "2", "3", "4");
List list = dc.getList("myList");
// At this point, you'll get a single element list containing only "1"

Scanning the bug DB, it looks like there was a problem earlier with this.  Perhaps a regression?
 Or (hopefully!) I'm doing something wrong?  I haven't changed the delimiter or whether it
should be evaluated from the defaults for a new DBConfig.

> I've found a bug where adding a list property to a BaseConfiguration, then copying that
full BaseConfiguration to a DatabaseConfiguration, the list is lost and only the first element
is copied to the destination DatabaseConfiguration.  For example:
> BaseConfiguration bc = new BaseConfiguration();
> bc.addProperty("myList", Arrays.asList("1", "2", "3", "4");
> DatabaseConfiguration dc = new DatabaseConfiguration(...);
> dc.copy(bc);
> List list = dc.getList("myList");
> // At this point, you'll get a single element list containing only "1"
