JOSM Error Duplication

Beerforfree · 2011-03-01T00:36:47.000Z

It seems that JOSM tends to duplicate nodes, ways and even relations when working on lower zoom leves, it happend to me when building relations (turn restrictions, areas). Other members have complaint about the same in the past and I thought it was their unexperience in using the tool
Although the correct node or way is selected JOSM seems to pick up near objects as well. I haven’t been able to find the way to reproduce the issue but I will pay more attention to find a pattern

Regards

When you can find a pattern for that error, please also tell us what version of JOSM you are using.

And have you already investigated all tickets (open and closed ones) about JOSM at http://josm.openstreetmap.de about that error?

I’m using the latest stable version available, the newest one is gonna be released on March 5th. I haven’t looked to any tickets. Perhaps it is a problem with the API/server, who knows

We haven’t been able to find a pattern until yet; one of our mappers made a SW to find duplicated ways. Here the results for Argentina. Most of them made by myself in the month of February and related with some kind of relation, either a turn restriction or a mulipolygon (mostly turn rest). I will let them as they are for a while before fixing them

It’s very strange that all duplication happened almost at the same time and I can’t say they were my first ones so as to blame my unexpirience, ha ha ha
