how to use request parameter with special character in HTTPService - 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>

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>

                    <lr xsi:type="xsd:string" />
                    <ie xsi:type="xsd:string">latin1</ie>
                    <oe xsi:type="xsd:string">latin1</oe>
