[jira] Commented: (CONFIGURATION-328) XMLConfiguration addNodes() not behaving correctly

["vivek (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CONFIGURATION-328?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12597827#action_12597827 ]

-------------------------------------

Emmanuel,

   Could you let me know if there is any workaround for this issue or if I can do things differently to make it work? It would be nice if you can give me a patch that I can apply to my local build or let me know what needs to be changed in the XMLConfiguration so I can make my own build.

Thanks,
-vivek

> Things used to work fine in 1.3, but now when I'm trying 1.5 my JUnit test suite is breaking when adding new properties. Here is what I'm doing,
> 1) I already have a configuration as following,
> {code:xml}
>  <test>
>   <property name="isOk">
>     <value>true</value>
>     <default>false</default>
>   </property>
>   <property name="intProperty">
>     <value>900</value>
>     <default>500</default>
>   </property>
>   <property extra="0" name="stringProperty">
>     <default>Bye</default>
>   </property>
> </test>
> {code}
> 2) Now I need to add two new properties under <test>,
> {code:xml}
> <property  name="newFirst">
>   <value>first</value>
> </property>
> <property name="newSecond">
>   <value>second</value>
> </property>
> {code}
> 3) Here is the code I'm using,
>         a) First create a new HierarchicalConfiguration.Node
> {code:java}
> private HierarchicalConfiguration.Node createNode(String name, Object value)  {
>     HierarchicalConfiguration.Node node = new HierarchicalConfiguration.Node(name);
>     node.setValue(value);
>     return node;
> }
> {code}
>                   
>        b) Add the node to the list
> {code:java}
> List<HierarchicalConfiguration.Node> attrNodes = new ArrayList<HierarchicalConfiguration.Node>();
> Node attrNode = createNode(attrName, newPropertyName);
> attrNode.setAttribute(true);
> attrNodes.add(attrNode);
> {code}
>         
>        c) Call addNodes on XMLConfiguration,
> {code:java}
>     conf.addNodes(attrPath, attrNodes);
> {code}
> I run this in a look for each new property I need to add. For first property, I get element count for the test.property as 3 (conf.getMaxIndex(key)) - so I insert at test.property(3), which is right, but for the second property I get element count as 5 --> This is wrong, it should have been 4 (because I just added 1). 
> I check the saved the configuration file after adding those two new properties and it looks wrong too. Here is what I get,
> {code:xml}
> <test>
>   <property name="isOk">
>     <value>true</value>
>     <default>false</default>
>   </property>
>   <property name="intProperty">
>     <value>900</value>
>     <default>500</default>
>   </property>
>   <property extra="0" name="stringProperty">
>     <value>Hi</value>
>     default>Bye</default>
>   </property>
>   <property>
>     <name>newFirst</name>
>   </property>
>   <property>
>     <value>first</value>
>   </property>
>   <property>
>     <name>newSecond</name>
>   </property>
>   <property>
>     <value>second</value>
>   </property>
> </test>
> {code}
> The total element count for test.property gives me 7 ==> I was expecting 5.
> There seems to have some code change in 1.5 releated to addNodes (for ex., CONFIGURATION-287). I'm not sure if I need to change the way I was calling addNodes before. It works fine with 1.3, but 1.5 completely fails on adding new properties. 
> I do need 1.5 for other bug fixes ( CONFIGURATION-268 and some other), but I can't use it until the addNodes behave correctly. 
> Marking this as blocker as I'm blocked because of this issue. If there is a workaround then please let me know.
