I’m looking for a node that looks like “Local File Browser Configuration” node but that allows defining a not existing file. The idea is to configure the output file name on a component node and pass the information to the writer node.
well you can add String Configuration node into your Component where user have to give a name to new file. With Local File Browser Configuration user chooses directory and then using String Manipulation (Variable) node you combine two flow variables into one. Take a look at modified workflow.
