[Users] BPELException: Impossible to realize the following assignmen

[duffqiu]

I try the simple assign in BPEL:

        <assign validate="no" name="Assign">          
            <bpel:copy>
                <bpel:from>
                    <![CDATA[$input.payload/tns:input]]>
                </bpel:from>
                <bpel:to>                    
                    <![CDATA[$output.payload/tns:result]]>
                </bpel:to>
            </bpel:copy>
        </assign>

But I still got the error, could some one help me:
