Rule Engine Node concatenation

@Vincentsoy if you like more complicated conditions you can always use the Java snippet and just write them the way you like.

It’s just a little bit more setup and not so ‘KNIME like’ but does work perfectly well.

java snipped simple if else

I built this example from the previous one where you could use a combination of columns and Flow Variable in a simple Java Snippet. It might serve as another inspiration. [image] The code is like this: // make the incoming Flow Variable into a Java variable double v_input_factor; v_input_factor = $${Dinput_factor}$$; // convert the double Java variable into a string to use in the code // https://www.journaldev.com/18380/java-convert-double-to-string String v_input_factor_string = new Stri…

If it is just one condition also the simple Java Snippet might work:

Use Java Snippet to set rule for certain Row ID - also demonstrating the use...

If you still want more Java I have this collection:
