Hi
When you see struts-default.xml, you find out that the
paramsPrepareParamsStack call the interceptor params twice.

You can set up your struts-default.xml or in struts.xml define your own
modified interceptor stack:

<struts>
    <package name="manager" namespace="/" extends="struts-default">
        
        <interceptors>                 
            <interceptor-stack name="myStack">
                <interceptor-ref name="exception"/>
                <interceptor-ref name="servletConfig"/>
                <interceptor-ref name="params"/>
                <interceptor-ref name="prepare"/>
                <interceptor-ref name="checkbox"/>                
                <interceptor-ref name="conversionError"/>             
            </interceptor-stack>
        </interceptors>
                
        <default-interceptor-ref name="myStack" />
                                
        ...

I thought the problem was Prepare being called twice, not Params. 
Anyway, there's no need to specify a custom stack to avoid having the 
Params interceptor called twice; the default stack only calls it once. 
The paramsPrepareParams stack is *intended* to call Params twice.
