JOSM start numbering objects from -1 to minus infinity

[anonymous]

Hello

after some work, JOSM start numbering (id) objects (ways, segments) from -1 to minus infinity (-1, -2, etc.). Example:

<way id='-2' action='modify' visible='true'>

<seg id='27950738' />
<seg id='27950743' />
<seg id='27950748' />
<seg id='27950753' />
<seg id='27950759' />
<seg id='27950765' />
<seg id='27950770' />
<seg id='27950773' />
<seg id='27950777' />
<tag k='highway' v='tertiary' />
<tag k='name' v='Kleszczowa' />

</way>

Of course server think, that id='0' and return " got return: 412 with id 0 ".

Data was not downloaded from server - it was renumered (it looks, that it apply to modified data to) by JOSM!

<segment id='0' visible='true' from='31718370' to='31718075'>

<tag k='created_by' v='JOSM' />

</segment>

</osm>

Sorry, it looks, that all new objects have "minus" id :)

Uploading problem has other cause.
