I’m using KNIME 3.5.3 in Windows and when I use “Table Column to Variable” to generate a Flow Variable that I want to use to set a limit for the “Random Number Assigner” node, the latter does not seem to obey the Flow Variable. Under “Flow Variables”, I go to “minmax”, then select “MAX” where I specify the variable from “Table Column to Variable”. However what I get from “Random Number Assigner” reflects instead what was specified for Max - even though at the bottom of the window I see an alert telling me “The MAX parameter is controlled by a variable”. The Flow Variable is being passed as type double.
I also found that if I instead use the node “Random Number Assigner (Apache)” I can use this Flow Variable to set a limit to the random number range.
At this point I’m not sure if this is user error, something peculiar with my installation, or an actual bug. If someone else could try this in KNIME 3.5.3 for Windows that would be great.
