Similar to Python View output data table - KNIME Analytics Platform - KNIME Community Forum.
To summarise, I need rich context-aware UI, e.g. adding new rows showing non-null counts, distinct values, etc. This can be achieved by custom HTML/JavaScript, however, this can only be presented to users as an output_view, but I need to save user’s input and make into the node’s table output. However, the KNIME’s node model is such that the execute method is completed before the output_view is rendered.
Is there a way to do this “cleanly”? Perhaps implementing it the configure with this output_view, call it configure_view.
There are several hacks to workaround the current limitation. One pattern that I’m using a lot is to have a button in the output_view to save the user input to an external sink. The sink location is defined in the execute method and returned as a single cell table output. This way the next node will know where to load the user input. It’s so hacky though.
I’m surprised that this has not been “officially” solved. Or am I mistaken?
