In combination with a Generic Loop Start node, this node lets you execute the body of the
loop until a certain condition on one of the flow variables is met. In the dialog you can choose one of the
available flow variables and which condition should cause the loop to finish.
You can add more input and ouput tables using the “…” menu.
