"Problem with Feature Selection"

Hi,
I am trying to perform Feature Selection, then apply the reduced subset of features to a J48 tree and finally present the tree to the output.
As you will see i have the 'create_complete_model option' checked
Unfortunately *all* tutorials of feature selection in RM use either SVM or NearestNeigbours models which both do not return an output!
Here is my setting :
<operator name="Root" class="Process" expanded="yes">
<operator name="CSVExampleSource" class="CSVExampleSource">
<parameter key="filename" value="c::\MyDocuments\score.csv"/>
<parameter key="label_name" value="class"/>
</operator>
<operator name="FeatureSelection" class="FeatureSelection" expanded="yes">
<parameter key="selection_direction" value="backward"/>
<operator name="SimpleValidation" class="SimpleValidation" expanded="yes">
<parameter key="create_complete_model" value="true"/>
<operator name="W-J48" class="W-J48">
</operator>
<operator name="ApplierChain" class="OperatorChain" expanded="yes">
<operator name="ModelApplier" class="ModelApplier">
<list key="application_parameters">
</list>
</operator>
<operator name="Performance" class="Performance">
</operator>
</operator>
</operator>
<operator name="ProcessLog" class="ProcessLog">
<list key="log">
<parameter key="Generation" value="operator.LibSVMLearner.value.applycount"/>
</list>
</operator>
</operator>
</operator>
What am i doing wrong ? ???
