[jBPM Bpel] Example in the userguide and the actual example

[nazartm]

The Bpel 'hello' example in the user-guide has one inconsistency with the actual example project. The guide gives the following:

<assign name="ComposeGreeting" validate="no">
 <documentation>compose a greeting phrase</documentation>
 <copy>
 <from>concat('Hello, ', $request.name, '!')</from>
 <to part="greeting" variable="response" />
 </copy>
</assign>

The highlighted value is what Netbeans bpel designer will also produce. However, this does not work in jBPM bpel. Rather, the given hello example project changes the highlighted text into:

<from expression="concat('Hello, ', bpel:getVariableData('request', 'name'), '!')" />

And this works. Is there something I'm not seeing here? I figure the first one should also work but so far no luck. No errors are reported, it just hangs. Anyone else had this experience?
