After days of trying various things, I then began comparing my example to the quick starts. I found the issue is 'name' is not being initialized. I hacked the code and added <name xmlns=""/> and it resolved the issue.

<bpel:assign validate="no" name="Assign-Input2Request">
<bpel:copy>
<bpel:from>
<bpel:literal xml:space="preserve">
<tns:hello xmlns:tns="http://jboss.com/examples/ws/Hello" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<name xmlns=""/>
</tns:hello>
</bpel:literal>
</bpel:from>
<bpel:to part="hello" variable="HelloWSPartnerLinkRequest"></bpel:to>
</bpel:copy>
