Subject [jira] [Commented] (FLEX-35070) "for each" not working in XMLList
Date Mon, 11 Apr 2016 16:02:25 GMT

    [ https://issues.apache.org/jira/browse/FLEX-35070?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15235361#comment-15235361

Alex Harui commented on FLEX-35070:
-----------------------------------

If I'm reading the code correctly (I didn't put through the compiler), the code is trying
to iterate over the "list" variable which is of type '*'.  This is one of the caveats about
E4X in JS.  Without runtime support, we have to have stricter type information at compile
time in order to generate enough magic to make it work; in this case, by replacing the standard
for-each pattern with a call to elementNames because we can tell at compile time that the
variable is of type XMLList.

So, you might have to "convert" list via:

var xmlList:XMLList = list;
for each (item in xmlList)

In theory you can "cast" as well, but I haven't tested it in the compiler.

for each (item in XMLList(list))

or

for each (item in (list as XMLList))

> I don't have a full test case right now, but I believe the following will fail.
> var newList:XMLList = new XMLList();
> newList.appendChild(<foo/>);
> var xmlItem:XML;
> for each(xmlItem in oldList)
>   newList.appendChild(xmlItem);
> If necessary, I can put together a (non)working test case.
