Subject [jira] [Commented] (FLEX-33313) Cannot append child to xml
Date Fri, 25 Oct 2013 16:12:34 GMT

    [ https://issues.apache.org/jira/browse/FLEX-33313?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13805415#comment-13805415

Alex Harui commented on FLEX-33313:

A node can only have one parent, so I would expect xml2.appendChild(..) to re-parent <childNode>
and thus the results are correct.

Try adding toXMLString() output after xml2.appendChild() to see if childNode gets re-parented.

>             Project: Apache Flex
>          Issue Type: Bug
>          Components: .Unspecified - Framework
>    Affects Versions: Adobe Flex SDK 3.2 (Release), Adobe Flex SDK 3.3 (Release), Adobe
Flex SDK 4.6 (Release)
>            Reporter: Curtis Aube
> var xml1:XML = <node><childnode/></node>;
> var xml2:XML = <node/>;
> xml2.appendChild(xml1.childnode[0]);
> xml1.appendChild(<newnode/>);
> trace(xml1.toXMLString());
> Output:
> <node>
>   <childnode/>
> </node>
> Expected Output:
> <node>
>   <childnode/>
>   <newnode/>
> </node>
> Workaround:
> Make a copy of the childnode and append the copy to the second xml node.
> or
> Remove the childnode before appending it to the second xml node.
> Additional notes:
> When you hit this bug, it is very hard to debug since there is no apparent reason it
is happening and no stack traces. Another solution to this problem may be to just throw a
stack trace when you try to append the same xml to two different xml parents, so that it's
easier to find and fix the problem.
