Subject [jira] Commented: (CONFIGURATION-401) HierarchicalConfiguration does not support hierarchy from property files
Date Mon, 09 Nov 2009 16:57:53 GMT

    [ https://issues.apache.org/jira/browse/CONFIGURATION-401?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12775023#action_12775023
] 

Joerg Schaible commented on CONFIGURATION-401:
----------------------------------------------

I don't think this is a valid enhancement request. The format of the property files are defined
in the JDK as key value pairs and if you define the same key twice, you simply override the
first one. This is what you get from Properties.load and I think we should not behave differently.

> If you have hierarchy like this:
> persons.person.name=1
> persons.person.surName=2
> persons.person.phoneNum=3
> persons.person.name=4
> persons.person.surName=5
> persons.person.phoneNum=6
> persons.person.name=7
> persons.person.surName=8
> persons.person.phoneNum=9
> If I have a regular property configuration that loaded a file containing in the above.
then I transform into HierarchicalConfiguration  using: ConfigurationUtils.convertToHierarchical(configuration).
> The tree is not right.
> I can do this:
> hierarchicalConfiguration.subset("persons").subset("person(0)").getKeys()
> but this returned empty iterator:
> hierarchicalConfiguration.subset("persons").subset("person(1)").getKeys()
> Only the first person is available.
