  Hi,
  I don't experience any problems with that. Take a look at that process:

  <?xml version="1.0" encoding="UTF-8" standalone="no"?>
  <process version="5.0">
    <context>
      <input/>
      <output/>
      <macros/>
    </context>
    <operator activated="true" class="process" compatibility="5.0.8" expanded="true" name="Process">
      <process expanded="true" height="116" width="279">
        <operator activated="true" class="retrieve" compatibility="5.0.8" expanded="true" height="60" name="Retrieve" width="90" x="45" y="30">
          <parameter key="repository_entry" value="//Samples/data/Iris"/>
        </operator>
        <operator activated="true" class="adaboost" compatibility="5.0.8" expanded="true" height="76" name="AdaBoost" width="90" x="179" y="30">
          <process expanded="true" height="471" width="759">
            <operator activated="true" class="decision_tree" compatibility="5.0.8" expanded="true" height="76" name="Decision Tree" width="90" x="45" y="30"/>
            <connect from_port="training set" to_op="Decision Tree" to_port="training set"/>
            <connect from_op="Decision Tree" from_port="model" to_port="model"/>
            <portSpacing port="source_training set" spacing="0"/>
            <portSpacing port="sink_model" spacing="0"/>
          </process>
        </operator>
        <connect from_op="Retrieve" from_port="output" to_op="AdaBoost" to_port="training set"/>
        <connect from_op="AdaBoost" 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>
  

  Greetings,
    Sebastian
