--------------------------------------
Still an issue in Apache Flex 4.9.1
> XMLEncoder.isSimpleValue() method fails to detect decoded simpleContent
> objects correctly
> -----------------------------------------------------------------------------------------
>
> Key: FLEX-27476
> URL: https://issues.apache.org/jira/browse/FLEX-27476
> Project: Apache Flex
> Issue Type: Bug
> Components: RPC: General
> Affects Versions: Adobe Flex SDK 4.1 (Release)
> Environment: Affected OS(s): All OS Platforms
> Affected OS(s): All OS Platforms
> Language Found: English
> Reporter: Adobe JIRA
> Labels: easyfix, easytest
>
> Steps to reproduce:
> 1. Decode and then re-encode an XML file containing an element with
> <xs:simpleContent/> using XMLDecoder and XMLEncoder.
> The re-encoded XML should match the original source XML.
> (See code example at bottom of description)
>
> Actual Results:
> <simple xsi:nil="true" id="foo"
> xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"/>
>
> Expected Results:
> <simple id="foo"
> xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";>bar</simple>
>
>
> Workaround (if any):
>
> XMLDecoder uses mx.rpc.xml.SimpleContent internally to decode simple content
> into a dynamic object that behaves like a String (by overriding the valueOf
> and toString methods)
> XMLEncoder.isSimpleValue incorrectly evaluates these objects to false. This
> can be fixed by checking the type against value.valueOf() rather than just
> the value
> public function isSimpleValue(value:*):Boolean
> {
> value:* = value.valueOf();//this is change required
> if (value is String || value is Number || value is Boolean
> || value is Date || value is int || value is uint
> || value is ByteArray)
> {
> return true;
> }
> return false;
> }
