[SOLVED] Filter Examples Operator

RLynx

Filter Examples operator does not work anymore for filtering (real and integer) missing values, but it works for missing nominal values.
Here is an example:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<process version="5.2.008">
  <context>
    <input/>
    <output/>
    <macros/>
  </context>
  <operator activated="true" class="process" compatibility="5.2.008" expanded="true" name="Process">
    <process expanded="true" height="476" width="748">
      <operator activated="true" class="retrieve" compatibility="5.2.008" expanded="true" height="60" name="Retrieve" width="90" x="112" y="75">
        <parameter key="repository_entry" value="//Samples/data/Labor-Negotiations"/>
      </operator>
      <operator activated="true" class="filter_examples" compatibility="5.2.008" expanded="true" height="76" name="Filter Missing Duration" width="90" x="246" y="75">
        <parameter key="condition_class" value="attribute_value_filter"/>
        <parameter key="parameter_string" value="duration = ?"/>
        <parameter key="invert_filter" value="true"/>
      </operator>
      <operator activated="true" class="filter_examples" compatibility="5.2.008" expanded="true" height="76" name="Filter Missing Vacation" width="90" x="380" y="75">
        <parameter key="condition_class" value="attribute_value_filter"/>
        <parameter key="parameter_string" value="vacation = \?"/>
        <parameter key="invert_filter" value="true"/>
      </operator>
      <connect from_op="Retrieve" from_port="output" to_op="Filter Missing Duration" to_port="example set input"/>
      <connect from_op="Filter Missing Duration" from_port="example set output" to_op="Filter Missing Vacation" to_port="example set input"/>
      <connect from_op="Filter Missing Vacation" from_port="example set output" 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>

Do I miss something? It used to work just fine before... Thank you!

Hi,

unfortunately there seems to be a bug in the current version. We have fixed it and will release a bugfix version soon.

Best,
Nils

Hi,

here is a workaround for you until we have released the fixed version:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<process version="5.2.009">
  <context>
    <input/>
    <output/>
    <macros/>

    <process expanded="true" height="269" width="681">
      <operator activated="true" class="retrieve" compatibility="5.2.009" expanded="true" height="60" name="Retrieve" width="90" x="121" y="149">
        <parameter key="repository_entry" value="//Samples/data/Labor-Negotiations"/>
      </operator>
      <operator activated="true" class="generate_attributes" compatibility="5.2.009" expanded="true" height="76" name="Generate Attributes" width="90" x="313" y="165">
        <list key="function_descriptions">
          <parameter key="duration_missing" value="missing(duration)"/>
        </list>
      </operator>
      <operator activated="true" class="filter_examples" compatibility="5.2.009" expanded="true" height="76" name="Filter Examples" width="90" x="447" y="165">

        <parameter key="parameter_string" value="duration_missing = false"/>
      </operator>
      <operator activated="true" class="select_attributes" compatibility="5.2.009" expanded="true" height="76" name="Select Attributes" width="90" x="581" y="165">
        <parameter key="attribute_filter_type" value="single"/>
        <parameter key="attribute" value="duration_missing"/>
        <parameter key="invert_selection" value="true"/>
      </operator>
      <connect from_op="Retrieve" from_port="output" to_op="Generate Attributes" to_port="example set input"/>
      <connect from_op="Generate Attributes" from_port="example set output" to_op="Filter Examples" to_port="example set input"/>
      <connect from_op="Filter Examples" from_port="example set output" to_op="Select Attributes" to_port="example set input"/>
