Instead of using page refresh to update, I would suggest making use of WebSockets for dynamic updates. I've had a lot of success with this in a recent project.

I use several other products that embed Google Maps API and there is not issue with zooming in on those, but they don't get an auto page refresh in HTML headers.

Hi,

This is caused by a limitation in the map library. It doesn't seem to honour the setting to disable autorefresh, so our attempts to make it stop refreshing when there's a mouse hovering over the map are ignored by it!

Hello,

We're currently running Observium v19.6.9959. Lately (I'm afraid I'm not sure when this started), when we double-click to zoom in on an area it only stays zoomed in for at most 10 to 15 seconds. It then bounces back out to its default.

We're using Refresh time 5 minutes, Wikimedia map tiles, map height 500 pixels, Google API with our API key all set via the web interface.

Is anyone else seeing this? Have I missed a config option somewhere?

Thanks for any pointers.

Hi Adam,

I made myself a small work around for this issue. It's definitely not a perfect solution, but it helps a bit. (diff attached)

Basically I changed the leaflet.in.php to: - have a higher refresh interval (from 10 to 60 seconds); - Set higher ZindexOffsets for the red alert icon to come on top of the green ones. - Stop and start the map refresh by clicking on it (instead of just using mouse over. The browser seems to loose track of the position with the mouse over function)

I hope this may help somehow.

Best regards, Sergio

We don't use page refresh to update. The map library updates itself with geojson, but the library is doesn't seem to correctly pause updates when we call the function.

We can't use google maps because it requires a license.
