Disable bpel:selectionFailure Fault and Auto-create Target Path for Copy To Example

The following example shows the effect of enabling both Disable bpel:selectionFailure Fault (BPEL4WS 1.1 processes:

bpws:selectionFailure)

and Auto Create Target Path for Copy/To options.

For details on WS-BPEL 2.0 processes, see

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.

Var1 Sample Data

Var1 and Var2 Schema Snippet

<ns1:OrderInfo

 <ns1:OrderHeader>
  <ns1:OrdId>78</ns1:OrdId>
   <ns1:BillToInfo>
    <ns1:Name>Name1</ns1:Name>
    (Addr1 is missing)
    <ns1:Addr2>1 Main St
        </ns1:Addr2>

    <ns1:Zip>12012</ns1:Zip>
    <ns1:Cntry>USA</ns1:Cntry>
   </ns1:BillToInfo>
...

<xs:complexType
     name="AddressInfoType">
  <xs:sequence>
   <xs:element ref="ord:Name"/>
   <xs:elementref="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 Disable bpws:selectionFailure Fault
and Auto Create Target Path for Copy/To enabled
, the process terminates normally because the empty selection node is allowed, and the location path to the empty selection is built. A null value is added to

Addr1

during the assignment.
