Subject [jira] [Commented] (FLEX-33644) XMLEncoder improperly handles encoding the string "null".
Date Fri, 02 Aug 2013 20:37:48 GMT

    [ https://issues.apache.org/jira/browse/FLEX-33644?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13728071#comment-13728071
] 

Justin Mclean commented on FLEX-33644:
--------------------------------------

This is the cause of the issue (at the bottom of the encode method there a similar condition).

				var nullXML:XML = <root>null</root>;
				
				if (nullXML == null) {
					trace("Some XML is null");
				}

nullXML == null is true!	

Not 100% sure what the best fix is - suggestions welcome.

>          Issue Type: Bug
>          Components: RPC: General
>    Affects Versions: Adobe Flex SDK 3.0 (Release), Adobe Flex SDK 3.1 (Release), Adobe

> The following code returns an empty string:
>     var enc:XMLEncoder = new XMLEncoder();
>     enc.encode("null");
> However, SchemaMarshaller.marshall() correctly returns the string "null".
> I believe the problems is that XML.appendChild (as used in XMLEncoder.setValue) for some
reason treats the string "null" differently. I have no idea why.
