"[SOLVED] Nested Operators in Weka don't have ports to connect?"

I've been playing with Ensemble Models lately. When I try to use the "Meta" operators from Weka (say for instance W-Vote) I don't see inside the operators the input or output ports/connectors. Am I missing something basic?

Thanks in advance for any help

    Hi Ernesto,

    Weka Ensemble Models work with Weka classifiers only. You dont have to connect the classifiers, they will get the input automaticly. Here is an example: 

    <?xml version="1.0" encoding="UTF-8" standalone="no"?>
    <process version="5.1.014">
      <context>
        <input/>
        <output/>
        <macros/>
      </context>
      <operator activated="true" class="process" compatibility="5.1.014" expanded="true" name="Process">
        <process expanded="true" height="579" width="708">
          <operator activated="true" class="retrieve" compatibility="5.1.014" expanded="true" height="60" name="Retrieve" width="90" x="150" y="176">
            <parameter key="repository_entry" value="//Samples/data/Sonar"/>
          </operator>
          <operator activated="true" class="weka:W-Vote" compatibility="5.1.001" expanded="true" height="76" name="W-Vote" width="90" x="313" y="165">
            <process expanded="true" height="639" width="950">
              <operator activated="true" class="weka:W-KStar" compatibility="5.1.001" expanded="true" height="76" name="W-KStar" width="90" x="363" y="216"/>
            </process>
          </operator>
          <connect from_op="Retrieve" from_port="output" to_op="W-Vote" to_port="training set"/>
          <connect from_op="W-Vote" from_port="model" to_port="result 1"/>
          <portSpacing port="source_input 1" spacing="0"/>
          <portSpacing port="sink_result 1" spacing="0"/>
          <portSpacing port="sink_result 2" spacing="0"/>
        </process>
      </operator>
    </process>

    Regards,

    That was embarrasingly (for me :-)) simple. Thank you very much Nils.
