[josm-dev] BUG: 412 precondition failed

[Igor Brejc]

Hello,

I posted this on the JOSM wiki talk page and also added a TRAC ticket:

I'm using the latest jar file (v368) . When I try to upload the changes, 
JOSM uploads updated and modified objects, but when it starts to send 
info to server about deleted objects I get the following message box: 
Error while parsing: An error occured: 412 precondition failed. This 
happens every time I try to upload the info about the deleted objects.
This was not happening to me in previous (API 0.4) versions of JOSM. 
Just to be sure, I loaded a much bigger area, so the data I tried to 
modify was not overlapping the loaded boundaries. Also, the data I'm 
modifying has been freshly downloaded from the server, so there were no 
conflicts with other users.
If, after this error occurs, I save the data to file, then restart the 
JOSM, load that file back into JOSM and try to upload the changes, the 
same changeset is being uploaded to the server and the same error 
occurs. I can send the example of the file.

Cheers,
Breki
