[bpel-dev] Why the generate literal xmls is defferent when call a variab

[grid qian <grid.qian@xxxxxxxxx>]

Hi all,
I met a problem about the bpel assign element.
When I add a copy to a assign element, the editor will prompt you to see if you want to create an Initializer. If you click yes, you will get a Fixed value to the To element.
But I found a problem:
if the To variable is like:
   <xs:element name='hello' type='tns:hello'/>
   <xs:complexType name='hello'>
    <xs:sequence>
     <xs:element name='name' type='xs:string'/>
    </xs:sequence>
   </xs:complexType>
the generated literal is like:
<bpel:literal xml:space="preserve">
<tns:hello xmlns:tns="http://eclipse.org/examples/ws/Hello" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
</tns:hello>
</bpel:literal>

But if the To variable is like:
   <xs:element name='hello' type='tns:hello'/>
   <xs:complexType name='hello'>
    <xs:sequence>
     <xs:element minOccurs='0' name='name' type='xs:string'/>
    </xs:sequence>
   </xs:complexType>
the generated literal is like:
<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></name>
  </tns:hello>
</bpel:literal>


The first literal is not right for the ode runtime engine. The runtime engine need the second literal.

I don't know why there is no <name></name> in the first literal. The difference of the first and the second is just:  minOccurs='0' in <xs:element minOccurs='0' name='name' type='xs:string'/>.

Thanks!
