@robertkalasek I'm running into this issue with a set of models I built earlier this year, but I'm using the 'Add Join' function. Each of these models worked perfectly for me prior to the Pro version 3 update. Have you found a resolution to this issue?
- I have checked that the join fields are the same type, and even created a new field with identical field lengths (they were different, but again, these models worked previously).
- I tried using the 'Export Features' function directly after the 'Add Join' and was able to see the join table fields in the Output Fields, but those fields were not available in the Filter drop-down menu.
- I also tried removing all the (2) from the model elements and that made no difference either (see pics).
So it seems like the join is working, but it isn't allowing me to query/filter on that joined dataset.
I submitted a bug report but haven't heard anything yet.
