Flow Variables

Hi, 

Is there a way to input 2 flow variables into the same node? 

Thanks!

I think you can prepend a Java Snippet Variable or Rule Engine Variable node before it, both has a normal flow variable port an the hidden mouse ears. That way you can merge two sources of flow variables (and even create new ones).

There is also a Merge Variables node.

However, Flowvariables flow through the workflow. Hence, they will also be available in all following nodes.

Best, Iris

Thank you guys! Inputting the flow variable in a previous node worked well.

Feature request: It’s great that you can add input ports to the Merge Variables node but it would be simpler visually and for the user if you had a special port that accepts multiple inputs. The multiple chevrons means multiple input. See this example: image
