Unable to call getVariableData from java exec

Question

Hi,
I am trying to call getVariableData("inFile") from a java exec. However, I get the following error:
<2005-01-18 11:40:37,506> <DEBUG> <default.collaxa.cube.engine> <bpel._1_0.SyncHello__BPEL4WS_BIN$$BPELC_BxExe22::perform> error thrown

at com.collaxa.cube.engine.CubeEngine.performActivity(CubeEngine.java:3215)
at com.collaxa.cube.engine.CubeEngine.handleWorkItem(CubeEngine.java:1636)
In the .bpel file, I have declared the variable as follows:
<variable name="inFile" type="xsd:string"/>
I have assigned values to this variable in two different ways (using the assign tag and also through a java exec call):
<assign>
<copy>
<from expression="'inFile.txt'"/>
<to variable="inFile"/>
</copy>
</assign>
OR alternatively:
setVariableData("inFile", new String("inFile.txt"));
After this I attempt to call (this is the part that throws the error):
CubeDOMElement el = (CubeDOMElement) getVariableData("inFile");
The strange thing is that I am able to get the variable from inside an assign activity as follows:
<assign name="setOutputVars">
<copy>
<from expression="bpws:getVariableData('inFile')"/>
<to variable="output" part="payload"
query="/outputMessage"/>
</copy>
</assign>
This assign works perfectly and outputs the correct value.
Any suggestions would be greatly appreciated.
Thanks.

I have a similar problem, but I try to retreive a complex object.
The assign activity successfully copy data to the variable 'DMSPollingInput'.
Here is my code:
Element element = (Element) getVariableData("DMSPollingInput");
System.out.println("Receive Poll and execute enqueue ");
if(element==null) System.out.println("element is null ");
else System.out.println("element is not null ");
IDmsPollingsCollection requests =
IDmsPollingsCollectionFactory.createFacade(element);
if(requests==null) System.out.println("requests is null ");
else System.out.println("requests is not null ");
List dmsPollings = requests.getIDmsPollings();
int count = dmsPollings.size();
System.out.println("Poll size: " + count);
The count always equals to 0.
Please help
