How to access variable of 'Element' type, Element being comp

[meghanai_99]

Hello,

I have been trying to deploy a BPEL process that extracts number value from a variable declared as ElementType. The defintion of the element is

<xs:element name="parent">
 <xs:complexType>
 <xs:sequence>
 <xs:element name="child" type="xs:string" />
 </xs:sequence>
 </xs:complexType>
 </xs:element>

The variable declaration for this element is

 <variable name="parent" element="tns:parent" />

The expression I want to evaluate is something like this -

 <assign name="Calculate2">
 <copy>
 <from expression="bpws:getVariableData('parent', ?, '/tns:parent/tns:child)" />
 <to part="parameters" query="/ns8:UpdateItem/ns8:item/ns8:title" variable="aewebservices70_UpdateItem-UpdateItem" />
 </copy>
 </assign>

The reason I have provided '?' is there is no part name. I know you can directly write 'variable' and 'query' attributes but what if I want to use operator on that query e.g

number(/tns:parent/tns:child) div SomeOtherParent/SomeOtherChild

How does the BPEL look in that case? Assuming 'SomeOtherParent' is another element declared as complex type? I am using BPEL 1.1 specification.

Thanks,
Meghana

Try this.

bpws:getVariableData('parent')/tns:child

You should avoid the query parameter (even if the variable is a message) and use the above alternative instead. Besides providing a way to query non-message variables, it has an added benefit. The query is syntactically analyzed during deployment. In the function call, the query parameter is analyzed till runtime.

Many thanks Alex.

PS: We found number of issues while upgrading JBPM beta to JBPM GA on Oracle and SQL Server. They are mostly hibernate issues though. Just FYI. If you are interested I can send you detailed email about issues.
