A RapidMiner user wants to know the answer to this question: "Hey, I am connecting retrieve data operator to filter example, since I want to filter the missing values, I get no variable in the first cell of "enter value." I am attaching my XML process. Do you know why this is happening?"

<?xml version="1.0" encoding="UTF-8"?><process version="9.2.000"> <context> <input/> <output/> <macros/> </context> <operator activated="true" class="process" compatibility="9.2.000" expanded="true" name="Process"> <parameter key="logverbosity" value="init"/> <parameter key="random_seed" value="2001"/> <parameter key="send_mail" value="never"/> <parameter key="notification_email" value=""/> <parameter key="process_duration_for_mail" value="30"/> <parameter key="encoding" value="SYSTEM"/> <process expanded="true"> <operator activated="true" class="retrieve" compatibility="9.2.000" expanded="true" height="68" name="Retrieve" width="90" x="45" y="34"> <parameter key="repository_entry" value="//Local Repository/data/DataSet1"/> </operator> <operator activated="true" class="filter_examples" compatibility="9.2.000" expanded="true" height="103" name="Filter Examples" width="90" x="179" y="34"> <parameter key="parameter_expression" value=""/> <parameter key="condition_class" value="custom_filters"/> <parameter key="invert_filter" value="false"/> <list key="filters_list"/> <parameter key="filters_logic_and" value="true"/> <parameter key="filters_check_metadata" value="true"/> </operator> <connect from_op="Retrieve" from_port="output" to_op="Filter Examples" to_port="example set input"/> <connect from_op="Filter Examples" 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>

    Your XML is fine as I cannot reproduce this issue without an original dataset. If possible, can you provide the dataset

    Hi @dbabrauskaite and @sgenzer

    I checked it, I even tried different sample datasets provided in RM samples. The issue is with filter example operators as it is not detecting any attributes from the dataset.
