I have a ColdFusion Component (web service) that looks like...
<cffunction name="getEmployees" access="remote" output="false"
returntype="xml">
<cfxml variable="myxml">
<people>
<person>
<firstname>John</firstname>
<lastname>Smith</lastname>
<job>
<title>Doctor</title>
<description>blah blah blah</description>
</job>
</person>
<person>
<firstname>Jane</firstname>
<lastname>Doe</lastname>
<job>
<title>Lawyer</title>
<description>blah blah blah</description>
</job>
</person>
</people>
</cfxml>
<cfreturn myxml>
</cffunction>
and some Flex code that looks like...
<?xml version="1.0" encoding="utf-8"?>
<mx:Application
xmlns:mx="http://www.adobe.com/2006/mxml";
creationComplete="TestService.getEmployees.send();">
<mx:WebService id="TestService" wsdl="http://localhost/hr.cfc?wsdl";>
<mx:operation name="getEmployees" />
</mx:WebService>
<mx:Tree
id="myTree"
width="50%"
height="50%"
showRoot="false"
dataProvider="{TestService.getEmployees.lastResult}"/>
</mx:Application>
But what I get is a Tree that looks like:
Flex doesn't seem to be able to extract the XML from the SOAP message, which
is just SOAP XML wrapping my XML data.
Changing the Operation's resultFormat from "e4x" to "xml" to "object"
changes the amount of junk in the Tree, but doesn't fix the problem. As a
matter of fact, it works best when I leave off this attribute and let the
Operation decide what resultFormat to use.
Casting lastResult as XML or XMLList doesn't seem to help either, and
neither does
ArrayUtil.toArray(TestService.getEmployee.lastResult)
Is there something I need to do to the lastResult to get it to work in
Trees, DataGrids, etc? Like cast it as some other data type? Why doesn't
e4x parse the SOAP message properly and extract my XML?
Just about every example I can find out there shows people using HTTPService
to pull back just the XML data without the SOAP webservice stuff, or else
shows how to create XML inside the mxml code itself using <mx:XML> but I can
find nothing that shows how to return XML from a CFC web service and
use/parse it in Flex properly (as easy as, say, a CFC that returns a Query
object.)
