When I go to File → Preferences → KNIME Explorer and I select or unselect (ticking the box) a MountID (for example LOCAL, EXAMPLES, My-KNIME-Hub) the changes are not correctly applied.
To be precise, the changes are saved when you unselect a MountID. But, if you want to select again a MountID, the changes are not saved. So I am unable to work with the MountIDs that I have unselected previously.
In my case, I have unselected LOCAL & My-KNIME-Hub for experimentation purposes and now I cannot undo my action. Meaning that LOCAL and My-KNIME-Hub do not appear anymore in the KNIME Explorer. I have tried to selected → Apply and Close, and nothing happens.
Any recommendation about how to proceed? I have restarted KNIME, the client, etc. And nothing. It is quite critical because currently I am unable to use KNIME with my LOCAL MountID. I can only use the EXAMPLES MountID because is the only one I have not unselected previously.
click apply; observe that they are removed from KNIME Explorer window.
click apply and close.
File>Preferences>KNIME Explorer
select My-KNIME-Hub and LOCAL.
click apply; observe that they reappear in KNIME Explorer window.
click apply and close.
Open a workflow from the LOCAL repo.
In the end, I was unable to reproduce your issue.
Please verify which version you are on;
if it is the latest, please confirm if you upgraded from a previous version via File>Update KNIME, or if you unzipped/installed via other means.
You may wish to download the zip archive from [1] and unzip it in a separate directory and test if you get the same results there, or if you are unable to repro as I was.
If your main install is on 4.5.2 and a fresh unzip copy doesn’t repro then maybe there is an issue with the particular installation (thus reinstallation may resolve.)
Clever solution. I’ll see about testing further to see what might put the preferences into a state where it doesn’t allow the mountid preferences to be updated, but I’m glad that you were able to resolve it through a manual export/tweak/reload of prefs.
