"How to loop through all values in a nominal set"
Hi everyone.
The Loop Values operator's wiki states throughout that it iterates over "all the possible values of the selected attribute".

The Loop Values operator's wiki states throughout that it iterates over "all the possible values of the selected attribute".
In view of this, I expected the process
<?xml version="1.0" encoding="UTF-8" standalone="no"?>to print to the console:
<process version="5.3.008">
<context>
<input/>
<output/>
<macros/>
</context>
<operator activated="true" class="process" compatibility="5.3.008" expanded="true" name="Process">
<process expanded="true">
<operator activated="true" class="generate_data_user_specification" compatibility="5.3.008" expanded="true" height="60" name="Generate Data by User Specification" width="90" x="45" y="75">
<list key="attribute_values">
<parameter key="a" value=""hello""/>
</list>
<list key="set_additional_roles"/>
</operator>
<operator activated="true" class="add" compatibility="5.3.008" expanded="true" height="76" name="Add" width="90" x="179" y="75">
<parameter key="attribute_name" value="a"/>
<parameter key="new_value" value="world"/>
</operator>
<operator activated="true" class="loop_values" compatibility="5.3.008" expanded="true" height="76" name="Loop Values" width="90" x="313" y="75">
<parameter key="attribute" value="a"/>
<process expanded="true">
<operator activated="true" class="print_to_console" compatibility="5.3.008" expanded="true" height="76" name="Print to Console" width="90" x="112" y="30">
<parameter key="log_value" value="%{loop_value}"/>
</operator>
<connect from_port="example set" to_op="Print to Console" to_port="through 1"/>
<connect from_op="Print to Console" from_port="through 1" to_port="out 1"/>
<portSpacing port="source_example set" spacing="0"/>
<portSpacing port="sink_out 1" spacing="0"/>
<portSpacing port="sink_out 2" spacing="0"/>
</process>
</operator>
<connect from_op="Generate Data by User Specification" from_port="output" to_op="Add" to_port="example set input"/>
<connect from_op="Add" from_port="example set output" to_op="Loop Values" to_port="example set"/>
<portSpacing port="source_input 1" spacing="0"/>
<portSpacing port="sink_result 1" spacing="0"/>
</process>
</operator>
</process>
But it only prints
hello
world
Is there a way in which I can iterate over the entire nominal set of the attribute, even those values that do not appear in the particular data currently provided?
hello
