Chris Martin commented on FLEX-34878:
-------------------------------------
Adjusted description of the issue. Determined that it is more accurate to say
that we will receive null only if all locales set in the localeChain property
are not compiled in. Basically resulting in the inability to find the
appropriate string value to return.
> error property of NumberFormatter returns null and not it's default value

> Key: FLEX-34878
> URL: https://issues.apache.org/jira/browse/FLEX-34878
> Project: Apache Flex
> Issue Type: Improvement
> Reporter: Chris Martin
> Assignee: Chris Martin
> Priority: Trivial
>
> Steps to reproduce:
> Build an application from the following code:
> {code:actionscript}
> <?xml version="1.0" encoding="utf-8"?>
> <mx:WindowedApplication xmlns:mx="http://www.adobe.com/2006/mxml";
> layout="absolute" creationComplete="onCC();">
> <mx:Script>
> <![CDATA[
> import mx.formatters.NumberFormatter;
> private function onCC():void
> {
> var nf:NumberFormatter = new NumberFormatter();
> nf.precision = 2;
> resourceManager.localeChain = ['zh-Hans'];
> trace("number:"+nf.format(1/3));
> trace("error: " + nf.error);
> }
> ]]>
> </mx:Script>
> </mx:WindowedApplication>
> {code}
> Compile the application but do not compile in a locale resource set for
> zh-Hans. Only compile in 'en_US'.
> Test the application and note that the first trace statement will return
> blank and the second trace statement of the error property returns null.
> Because the zh-Hans locale was not compiled in we are unable to know what
> language to use to display the default error message of "Invalid format".
> Would like to add in a comment into the asdocs informing the user that if
> none of the locales in the localeChain property of the ResourceManager are
> not compiled in, then it will return null.
