[josm-dev] How to use DownloadTask in Python/Jython

[Jo]

Hi Paul,

Many thanks for your help. Unfortunately I gave up on trying to get it to
work. So I rewrote the script in such a way that the user can decide to
download data and if they do, then the script will terminate and they'll
have to run it once again, so it can perform the rest of the work.
(Comparing bus stops in route relations; some being template routes from an
external source, the others from the existing data. Then presenting them,
so they can be matched and handed to another script, which updates the
existing route based on the template).

I can see that the download is occurring and even completes, and I can even
manage to get several pieces of code run concurrently (which may come in
handy some day, learned a new trick there), but the freshly downloaded data
only gets merged into the layer after the script terminates.

Cheers,

Jo
