how to send same payload to multiple component in mule?

I have a problem where one mule component transform the payload object into some other value. Ex: Suppose my payload contain student object. Initial value of Student name=a;

My first mule component change student name to x;

Student s=new Student();
s.setName("x");

My second mule component receive name as X from payload. But I want original value as 'a'. I tried checking original payload of mule but that value is also changed..

<flow .....
   <component> </component> // 1st component
    <component></component> //2nd component
</flow>

I want same payload(original) (Student object with name a) in both the component..how can I do that? I have checked original payload and that has been transformed..

Thanks

Mule also use scatter gather component, which sends the payload to multiple endpoints in parallel. This component has been introduced from Mule 3.5.0 .. example :

<scatter-gather doc:name="Scatter-Gather" timeout="6000">
 <flow-ref name="flightBroker1" />
 <flow-ref name="flightBroker2" />
 <flow-ref name="flightBroker3" />
</scatter-gather>

Here is the reference :- https://developer.mulesoft.com/docs/display/current/Scatter-Gather

You can use <all> to send same payload to different components like 

<flow .....
   <all>
       <component> </component> // 1st component
       <component></component> //2nd component
   </all>
</flow>

or, a different way to approach same thing is to store the original payload in a variable and then replace the payload with the previous one like:

<set-variable variableName="originalPayload" value="#[message.payload]" />

and then,

<set-payload value="#[flowVars.originalPayload]"/>
