Auto-create Target Path for Copy To Example

The following example shows the effect of enabling and disabling the Auto Create Target Path for Copy/To option.

For details on WS-BPEL 2.0 processes, see Using the Process Developer Create XPath Extension.

For a description of this BPEL4WS 1.1 preference, see Simulation Preferences.

Code sample
:

<assign>
  <copy>
    <from part="OrderInfo" query="/ns1:OrderInfo
        /ns1:OrderHeader/ns1:BillToInfo/ns1:Addr1"
         variable="var1"/>
    <to part="OrderInfo" query="/ns1:OrderInfo
        /ns1:OrderHeader/ns1:BillToInfo/ns1:Addr1"
         variable="var2"/>
  </copy>
</assign>

In the code sample, the Assign From/To query is for an optional element, as shown in the schema snippet below.

Schema Snippet for Var1 and Var2:

<xs:complexType name="AddressInfoType">
  <xs:sequence>
   <xs:element ref="ord:Name"/>
   <xs:element ref="ord:Addr1" minOccurs="0"/>
   <xs:element ref="ord:Addr2"/>
   <xs:element ref="ord:City"/>
   <xs:element ref="ord:St"/>
   <xs:element ref="ord:Zip"/>
   <xs:element ref="ord:Cntry"/>
  </xs:sequence>
 </xs:complexType>
<xs:element name="BillToInfo" type="ord:AddressInfoType"/>

With Auto Create Target Path for Copy/To disabled, the simulation ends in a fault because

Var1

contains the query selection node, but it cannot be assigned to the

Var2

query selection node because the location path is missing.

With Auto Create Target Path for Copy/To enabled, the process terminates normally because the location path for

Addr1

is built, and the value is added to

Addr1

during the assignment.
