how to use request parameter with special character in HTTPService - Flex - apache-flex

Question

Currently I have :
<mx:HTTPService id="userLogin" url="https://api.localhost/api/user/login/" method="POST" resultFormat="e4x" result="doSomeThing(event)">
<mx:request>
<email>{loginUser}</email>
<password>{loginPassword}</password>
</mx:request>
</mx:HTTPService>
instead of this I have params like userCredentials.email and userCredentials.password.
I tried this but it odesnt work.
<mx:HTTPService id="userLogin" url="https://api.localhost/api/user/login/" method="POST" resultFormat="e4x" result="doSomeThing(event)">
<mx:request>
<userCredentials.email>{loginUser}</userCredentials.email>
<userCredentials.password>{loginPassword}</userCredentials.password>
</mx:request>
</mx:HTTPService>

Answer 1

let us know if its work for you:
<mx:HTTPService id="userLogin" url="https://api.localhost/api/user/login/" method="POST" resultFormat="e4x" result="doSomeThing(event)">
<mx:request>
<userCredentials>
<email>{loginUser}</email>
<password>{loginPassword}</password>
</userCredentials>
</mx:request>
</mx:HTTPService>
also did you see this from http://livedocs.adobe.com/flex/3/html/help.html?content=data_access_5.html :
<?xml version="1.0"?>
<!-- fds\rpc\WebServiceSOAPRequest.mxml -->
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" verticalGap="10">
<mx:WebService id="ws" wsdl="http://api.google.com/GoogleSearch.wsdl"
useProxy="true">
<mx:operation name="doGoogleSearch" resultFormat="xml">
<mx:request format="xml">
<ns1:doGoogleSearch xmlns:ns1="urn:GoogleSearch"

<oe xsi:type="xsd:string">latin1</oe>
</ns1:doGoogleSearch>
</mx:request>
</mx:operation>
