7306	conflict management creating duplicate nodes, validator not finding all problems at once with r4857	dieterdreist	team	"When I tried to upload a changeset JOSM told me that one item was supposedly deleted on the server and asked me to synchronize the dataset. First I tried to synchronize only one item, but for continuous error alerts which followed subsequently I did ""synchronize"" the whole dataset. This led to masses of duplicate nodes and ways and one conflict in a way with 0 members. I resolved the conflicts (no member conflicts, only tags).
After this I tried to upload my fixed data but got this message: ""Failed to upload to changeset 10,474,051 because it has already been closed on 1/23/12 12:44 PM"".

Another problem I noticed: the validator seems to find errors and warnings only partially. Every time I hit ""validation"" after I fixed some problems like duplicate nodes (I usually merged them manually) I got new issues which hadn't been there before.

In another attempt I got this problem: ""Failed to upload data to or download data from 'http://api.openstreetmap.org/api/0.6/' due to a problem with transferring data. Details(untranslated): Read timed out""

And yet another try (uploading to _open_ changeset) led to this: ""Uploading failed because the server has a newer version of one of your nodes, ways, or relations. The conflict is caused by the relation with id 1,983,550, the server has version 3, your version is 2.  Click Synchronize relation 1,983,550 only to synchronize the conflicting primitive only. Click Synchronize entire dataset to synchronize the entire local dataset with the server. Click Cancel to abort and continue editing""

I did ""cancel"" now, to avoid further manual fixing of duplicates.
