[Talk-ca] Upload error - newer version exists

[Samuel Longiaru]

Good morning Everyone...

Thanks for the tips on the mid-line handles and how to merge points in
JOSM.  Very handy.  

I spent some time editing four CanVec files I imported this weekend and
ran into a problem that I hadn't seen before.  I must have done
something procedurally that I should stay away from as I eventually just
wound up abandoning about an hour's work.  No biggie.  But maybe someone
can clue me in on what may have happened and how I might avoid it in the
future.

Last night, I did a merge of CanVec and existing OSM data, trying to
make sure first to remove from the CanVec data layer anything that was
already in the OSM data.  The upload went fine with some warnings...
which I was going to address today with some edits.  Anyway, this
morning, after doing some editing, checking the Validator and so on...
the upload of the edits failed with the error that I was trying to
upload a node (and only one node was listed) that was older than a node
currently existing.  I was trying to replace a Version 2 node of mine
with a Version 1 node.  JOSM asked if I wanted to synchronize and I said
YES.  Tried to upload again and it failed with  more errors.  Something
was definitely wrong with my edit and so to avoid corrupting the
existing database, I bailed at that point.

Here's where I think I may have messed up.  While editing, one of the
warnings was that there were duplicate nodes.  Apparently there was a
short section of road that I had originally missed removing from the
CanVec data before merging.  While sorting out which way to remove,  I
got a message that said that the selected way extended into an area that
had not been downloaded and asked whether I wanted to download
additional data.  YES.  Then I made sure to select only the duplicate
from the CanVec data and deleted that, leaving the old OSM road intact.
I would have thought that was the way to go.  I merged some corner nodes
and so forth... but nothing else was really out of the usual edit
routine. 

So did I screw up by downloading additional data during an edit?  Is
that to be avoided?  The database thing is rather mysterious and magical
anyway so I don't have a real grasp as to what is actually going on
behind the scenes.  Or is there something else that I did that could
trigger this "writing older-over-newer" kind of error?

Thanks,
