[watmildon]

What steps will reproduce the problem?

I have not tested this to see if it repros with exactly this or if you need more info.

1. osm-download.bounds 35.1812448;-96.8455124;35.2244471;-96.748867

Overpass Query:

[out:json][timeout:150];
// gather results
(
  nwr["waterway"]({{bbox}});
  nwr["natural"]({{bbox}});
);
// print results
out body;
>;
out skel qt;

2. scrolling and hovering over elements

What is the expected result?

no errors

What happens instead?

exception

Please provide any additional information below. Attach a screenshot if possible.

[taylor.smock]

I don't know what is causing this, and I was unable to reproduce.

Can you share C:\OSM\mapwiaipaintstyle and %UserProfile%\Address Tags Validator - Highlight unaddressed?

Alternatively, it is possible that one of the remote paintstyles caused the issue and has been updated since you installed it. If this is the case, JOSM Preferences -> Advanced Preferences -> search for mirror. and reset all of the entries -> restart JOSM.

I've attached those file (also realized I have some mapstyle cleanup to do). I've been doing waterway cleanup for a while but recently added the Waterways paint style... No issues before then but I don't know if that's purely coincidental. No other style changes in the interim.

I'm playing with it now to see if I can get a better repro.

I reset the mirrors, had only JOSM Default and Waterways paint styles active, and eventually after clicking around, zooming, scrolling a large partial download I got the error to pop again. I have tried repeating the final bit of scrolling on a fresh launched JOSM but it didn't repeat.

It may be obvious but I figure no harm in saying, once the error happens, it will pop a bunch of them as I move the mouse around any part of the map view port.

I am still on the hunt.

I managed to get it to repro without the "natural" portion of the original download but again... not in a reproducible way. Ugh. Gonna have to call it a night.

wiki:Styles/Waterways is a relatively new style (3 days old). I'll see if I can figure out what is causing the problem.

EDIT: I wasn't able to figure anything out -- nothing jumped out to me when I was scanning through the source for the paintstyle.

not in a reproducible way

I hate it when I cannot reliably reproduce something -- how do I know I actually fixed it. I might think I have, but maybe I'm wrong.

Closed as duplicate of #16348.
I found a duplicate in Trac (see #16348).

Bugs withoout clean repros are a super hassle. I am very sympathetic to that. I'll keep an eye out and if something crystalizes I can drop it in that linked issue.

I'm also happy to run a modified JOSM with some extra diagnostics if you think that's helpful. Just brainstorming here.
