Emmanuel Bourg commented on CONFIGURATION-342: ---------------------------------------------- I suggest two solutions to this issue: # either drop the unique constraint on the key and allow several entries with the same key # concatenate the values with a separator The fist solution is probably easier, but the list order will be lost (unless the results are sorted by rowId, but that's very database specific). > DatabaseConfiguration.copy() loses list/array values > ---------------------------------------------------- > > Key: CONFIGURATION-342 > URL: https://issues.apache.org/jira/browse/CONFIGURATION-342 > Project: Commons Configuration > Issue Type: Bug > Components: Type conversion > Affects Versions: 1.5 > Reporter: Scott Wells > Fix For: 1.8 > > Attachments: ConfigurationUtil.java > > > 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: > {code:java} > 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" > {code} -- This message is automatically generated by JIRA.
