Hey there,
I just installed the latest update (KNIME 5.5.0) and now I can’t configure my nodes anymore. Neither double clicking, right clicking, clicking F6 work and the configuration cogwheel does not appear:
The rule engine I can configure just fine:
Nodes like CSV reader also work.
Does someone know what is going on here?
Thanks!
In 5.5 you should have a configuration panel for nodes with modern interface on the right of your screen…
Ohh, wow ok. It was closed and I did not see it. Thank you!
Hi @KasimirNepomuk, yes, with 5.5 dialogs with a modern UI are embedded by default. You can also change it back (for now) in the preferences
Hi @KasimirNepomuk, You won’t be the only one to be confused by this behaviour with 5.5.
I remain hopeful that there will be a future patch so that pressing the old node-configuration shortcut key or double clicking on the node will cause the config panel to open if it is currently closed (for modern nodes with embedded config). It seems like the “obvious” action given there is no other visual feedback of how to configure it when the panel is closed.
I continue to get caught out by it even though I’m aware of the issue! 
As I have a suspicion that this is a subject that will be coming back a few times in the future, I’m posting some screenshots on the way this config panel currently works, and hopefully it will be of use.
For those who haven’t spotted it, the “embedded config” is a panel that appears on the right of the modern UI application screen, allowing compatible (modern UI) nodes to be configured via this panel instead of via a popup window. There are some advantages to this, one being that the window is no longer necessarily “modal” and you can potentially interact with other windows with the mouse while it is open.
However, a current unfortunate side-effect is that there is a counter-intuitive difference between the Modern UI and Classic UI nodes, in that an unfamiliar user may not see where you now go to configure a modern UI node if the panel is in a closed state, as the familiar double-click action or shortcut key don’t work for those nodes.
If it is open, you can close it by clicking here:
If it is closed you will see an arrow on the side bar that you can click to open it:
I agree with the original side-effect you mentioned around confusion between the two types of nodes. Just as a general comment, this update makes development on small screens harder than the previous configuration method.
