Hello dawg,
What I suggested is same with Greg. A historical thread in this mail
list has clarified how to intialize variables in ODE:
http://old.nabble.com/Must-BPEL-complex-variable-initialization-use-extension-mechanisms--tc22904186.html#a22904186
In short, we should "initialize the entire target variable using the complete
element in the literal from-spec"
For example, given the declaration of the variables:
<variables xmlns:ws0="http://example.com/service01.wsdl";>
... ...
<variable name="_a" element="ws0:elemA" />
<variable name="_b" element="ws0:elemB" />
<variable name="_c" element="ws0:elemC" />
<variable name="_a2" element="ws0:elemA2" />
</variables>
and the schema:
<schema targetNamespace="http://example.com/service01.wsdl";
xmlns="http://www.w3.org/2001/XMLSchema";
elementFormDefault="qualified">
... ...
<element name="ResultInfo">
<complexType>
<sequence>
<element name="elemA">
<complexType>
<sequence>
<element name="elemB">
<complexType>
<sequence>
<element name="elemC" type="string"
maxOccurs="unbounded"/>
</sequence>
</complexType>
</element>
</sequence>
</complexType>
</element>
<element name="elemA2" type="string"/>
</sequence>
</complexType>
</element>
</schema>
We should initialize $_b as:
<copy>
<from><literal>
<svc01:elemB xmlns:svc01="http://example.com/service01.wsdl";>
<svc01:elemC/>
</svc01:elemB>
</literal></from>
<to>$_b</to>
</copy>
Then we are permitted to copy some values to $_b or its child.
Hope it helpful to you.
