Sorry for not documenting better. I just wanted to put a feeler out there to see if someone else has the same issue. I did run it down last night and this is what I found.
- I do not have a list pointing to that View, I did see that code as well and I tried that. When setting up a list to the existing view (i.e. pick existing table or view from my second database connection) I did notice the elements are not created automatically anymore. That maybe another issue to investigate some day.
- Not sure why I got the label instead of the text, didnt look into it since I was trying to make it go away.
Anyway long story short, V3 seem to to do the same thing and gives that warning in the Front-end. In V3 I had setup a list without a group for that view in it, for performance reasons and to suppress the warning.
In V4 the issue was when having ; 2 lists with the same name and when using SEF, it was opening the wrong list, even though the menu indicate the correct form number. The link ended up as "/index.php/devices-expert/list/15"
I made it go away by renaming the list and after that the router confusion was gone. An even by renaming the form back just now, I cannot reproduce it anymore, looks like something got corrected in the DB.
