Hello,
As this bug (bugs) are quite difficult to repeat, I would like to notify KNIME team about several problems related to new implementation of "node" settings memory, that recently have been noticed by me during my work.
1) Node (groupby for example but also others like filtering nodes) remembers the columns from previous nodes even when they have been discarded (they are still on the list).
2) Copying node seems to work on previous dataset from previous node even when being connected to completely different dataset (node) - I had this error couple of times
3) General problems with past settings for copied nodes.
Nodes taken from the list behave in the correct way, what makes me thing that maybe this new feutures related to node memory are a little bit broken.
My version of KNIME - 2.8 - btw anyone else had this problems?
