Hi @iCFO , that sounds like a useful tip, but when you say “swap out a node”, do you mean replace an existing node on the workflow with a different node (e.g. from the palette ) whilst keeping the node connections intact?
If so, it was only recently that I discovered you can do this using drag and drop… a very specific drag and drop.
Say I have the following:
and I want to replace the central String Manipulation node with a String to Number node.
I find the String to Number node in the Node repository:
Then drag it onto the String Manipulation node.
At the exact point that I have dragged onto the String Manipulation node, the node’s colour “inverts”
When it is in this altered-state, I drop the replacement node…
and KNIME swaps the nodes whilst retaining connections
