Hello KNIME team,
I have some problems adding an Integer type flow variable as a constant value column. Since a picture is worth a thousand words, please take a look at the attached screenshot as well as the correspondent workflow.
Best,
Marc
It sounds like a bug...
Before to use the variable you must run the node by inserting manually the value 1.
After this you can insert the variable and it works.
Thanks for the tip.
This is part of a bigger issue that we are aware of regarding the initialization of node settings before they are over-written by flow variables. In most cases, some valid default value will need to be entered into the node dialog before that setting may be over-written with a flow variable. We argree that this is confusing, but for now at least, it is a necesarry evil.
