Hi, I have been experiencing these kinds of errors recently, among them below is one! Not sure why the error has come up although the name is rightly formatted. Any known reasons? Note: The same Naming has been suggested in the learning path! Note: I have copied the name and then seeing this issue later after some time I manually enter the name it is getting saved! Thank you in advance!
This is obviously a bug. I had validation bugs in 10.1.1 for a different item. I would suggest upgrading to 10.3.0 to see if it still occurs. If you are on 9.x, upgrade to the highest 9 version (or an MTS, LTS, depending on the release strategy) . If it still occurs, lease send the details, including your Mendix Studio Pro version to firstname.lastname@example.org.
