I talked to the editing team - they logged a defect report to fix this in a future release.
Can you give us information/feedback on the "horrible procedure...for 1:n relates"?
Sure.
This is my data:
Goal: click on a point, read its attributes, read related attributes and open related media. Source files should be left as they are if possible in order to be easily editable and because they are used elsewhere.
To accomplish that, this is what I have to do in ArcMap after loading the shp and xlsx:
Now I can:
Now we try the same thing in AGP. Since I can't open media links directly like in ArcMap AFAIK, I have to use attachments:
Now I can do/see a fraction of what I can in ArcMap:
Alternatively, I could do this:
This more or less replicates what can be done in ArcMap, but you have to switch around between attributes and attachments. Since you can't open files directly from the attributes like in ArcMap, accidentally mixing up media is a problem because it doesn't show their corresponding attribute field (for example "before": image4r53653235465.jpg and "after": image4r53453235465.jpg, two files which would be easily distinguishable in ArcMap wouldn't be in AGP).
Compared to the single step I have to do in ArcMap and the flexibility/security it gives me, I would indeed call this "horrible". Of course, I could be just overlooking something and file opening functionality from ArcMap is included in AGP.
