Converting data layer to gpx layer failed

[anonymous]

What steps will reproduce the problem?

1. Record track with GPS logger GNS3000
2. Convert result to GPX by using gpsbabel
3. Load GPX file in josm
4. Convert GPX Layer to data layer
5. Edit GPX Layer deleting some nodes [5a. Save layer as OSM file, 5b. save layer as GPX file]
6. Convert GPX Layer to data layer

What is the expected result?

successfull conversion

What happens instead?

crash

Loading this file into josm and trying to convert the layer to GPX is a more direct way to reproduce the bug

Ticket #23000 has been marked as a duplicate of this ticket.

It looks like we aren't changing the values back to the "expected" values.

In 18753/josm:

Fix #23001: ClassCastException in GpxDrawHelper#calculateColors

This occurs when a working GPX file with HDOP information is converted to an OSM
Data Layer and back to a GPX Data Layer. This is fixed by (a) converting casts
for get operations to Number instead of Float/Integer and (b) actually
putting the number in the attribute map instead of a string.
