Worldmap panel is not rendered in view mode when using json endpoint location data

[xiaobeiyang]

Reproduce step:

1. Setup a dashboard use worldmap panel.
2. Set Location Data field to json endpoint.
3. View panel.
4. Refresh browser

Result:
Can't see the dashboard.
Note:
I can reproduce this issue on Chrome & Edge & Safari. Can't reproduce on latest Firefox.

I think jsonp endpoint has the same behavior.

I think I am having the same issue. If the json endpoint takes longer to respond than the query, there are no map points rendered. I was able to get it to work when the query I was using took a long time to respond ( longer than the json location response), but when I optimized my query to run faster this behavior started. The workaround I am using is to hit the refresh button after the locations have had a chance to load.

Dear @xiaobeiyang and @stevemandl,

thanks for bringing this up. We might have improved this behavior already within our fork [1,2] through. Its most recent version can be installed side-by-side to Worldmap like outlined below.

Please feel free to get back to me if this doesn't help. I will be happy to open a case for looking into the issue within one of the next development iterations then.

With kind regards,
Andreas.

I tried this and it did not fix the problem. However, the fix in #221 does fix the problem.

Dear @stevemandl,

thanks for letting us know. We will consider integrating this update within one of the next development iterations on our fork [1].

Dear @stevemandl @amotl
Thanks for verification & confirmation.

Dear Steve,

If the json endpoint takes longer to respond than the query, there are no map points rendered.

Thanks again for clarifying the behavior you are observing. We are now also tracking this within grafana-toolbox#53.

The fix in #221 does fix the problem.

As far as we can see, the essence of #221 is already integrated into the fork. However, there still might be dragons regarding timing/synchronicity.

With kind regards,
Andreas.
