    I have noticed this before, but I just corrected it. But now I have noticed it again. Sometimes a sighting doesn't have a location. I assume I entered a location at the time of entry, but it is not there now. Using 5.0.54. Picture attached. And you have my database from a few days ago.

    Hi David,

    Thanks for the picture. It did give me an idea as to how this might possibly happen. How I got here is: a) you cannot add a sighting without an attached location, and b) you cannot delete a location with sightings attached. How could this happen? You have a location with a name that is empty? Zero-length string.

    How does that happen? I am not sure, because I just tried to create a new location. Nothing in the user interface should allow this, and I have tried. So, I am thinking that there is a possible way when importing records, whether from eBird, AviSys, BirdBase or whatever, that allows for a location with zero length to be created.

    How you are able to seemingly enter a sighting with no location is that you leave the location field blank and because blank is the same as a zero-length-string, it matches on this errant location name and enters the sighting for you.

    Thankfully, I do have you database and was able to find this location. It is a child of your location Oregon Inlet Marina. To fix this issue, 

    1. Open the Location Maintenance window and locate and open location Oregon Inlet Marina.
    2. There you will find a location tree node with no name.
    3. Right-click on that node and choose 'Edit Location' from the popup menu.
    4. Now you can change that name to something recognizable.

    QED

    If that were true, then I should be able to leave the Location blank and it would take it. But it does not. "You have left a required selection empty: Location". I also get that if I enter a space for a Location.

    I did as you said and changed it to XXXX. Then I searched for XXXX. The troublesome record is the only one out there. I actually do not have anything for it to be changed to. So, I now have deleted that location. And taken care of the problem record. I still don't see how I could have used that location in the first place. But, oh well.

    You're right David. I don't know how that happened.

    Do you know where the record in question came from in the first place? Is it one you would have imported, or entered via the UI? 

    Let me know if you remember.

    Thanks,

    Jeff

    I understood you to say the bad location must have been imported. I have gone back to the spreadsheets that I guess I used for my original import years ago (not sure which one I used) Nothing had a blank. I went back to a 9/26/2017 copy of the database (before I made the 5.0 upgrade). It did not have the blank location. But the 7/28/2018 copy (before some other install) DID have the blank location.

    But that does not explain how that location got attached to that sighting record. I manually entered that. It is this year.

    Nice research David. I guess we just wait to see if it happens again. No one, that I can remember, has ever reported this problem - so it must be rare.
