latest version of QGIS fails to edit attribute table of GeoJSON file
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ margin-bottom:0;
}
I am using QGIS 3.6.4 and working with GeoJSON files. I have come across a very annoying problem. Whenever I try to add an attribute and assign values to it using the field calculator, the values will appear to update and the field looks correctly populated. However as soon as I exit out of the attribute table (while saving changes) and reopen it the entire column is converted to NULL.
I have tried playing around with the precision and width of the output field to no avail. I don't think this is related to coordinate system units since this is not a geometric operation of type $area or $length. It is more like Acol1+Bcol2.
Has anyone had such an issue before? Please help... I would have thought basic functionality like this is already well tested and bug free in QGIS....
EDIT
Other symptoms include:
- new field disappears if I remove the layer and add it again from file location, despite having saved layer changes....
- a separate geojson file called result.geojson.tmp is created and contains the modified attribute table. However my result.geojson is unchanged. Adding an attribute field and populating it should not create a new file but modify the current one in place... why does this happen?
- I have also attempted this with QGIS 3.6.1 - Same problem.
The problem appears to be under discussion in the QGIS issue tracker

U have this behavior each time u change the structure of a table ? ...

Apr 21 at 12:42
no, adding and deleting fields seems to work fine... I just can't edit the contents....
– user32882
Apr 21 at 12:43
And u never succeeded in editing the content when u were doing this ???

I would succeed before, but unpredictably so... Now it is systematically failing even after closing and reopening the whole program.

Don't waste your time like I did. This is a QGIS bug. I spent several days trying to solve this issue.
There is no solution at the moment.
I posted the same issue on QGIS bug report. I don't know what developers
did, but after version 3.2.3, GeoJSON files doesn't work on windows OS (it creates a temp file on the same location and all the edits only apply on temp file).
My suggestion is to downgrade to 3.2.3, I did this in our company and it works well.

the developers seem to be unable to reproduce it on their machines - if you follow the bug you can see what is happening. If you company is dependant on this functionality you can contribute sponsorship to get it fixed.

They did reproduce the issue. the reason why they were unable to reproduce it at the beginning is, they were trying on Linux while this is Windows problem, not Linux.
