Workflow: Chapter 5/Exercise 4


The goal of this exercise is to build a component that allows for interactive configuration through various Configuration nodes (Value Selection Configuration and Column Selection Configuration inside the component).

The Value Selection Configuration node allows to select a specific body type of a car and uses the created flow variable to overwrite the setting of the Row Filter.

The two Column Selection Configuration nodes allow to choose two columns (column 1 and column 2) which are passed on as flow variables to the Column Merger node. The Column Merger node then replaces the values in column 2 with the values from column 1.

Double click the component and change the configuration to see how it affects the data output.
