Support for Drupal 7 is ending on 5 January 2025—it’s time to migrate to Drupal 10! Learn about the many benefits of Drupal 10 and find migration tools in our resource center.Not sure where this error lies.
I have a map with a kml layer, if I user the recommended Openlayers version 2.11 the kml markers are not displayed initially, a JavaScript error is thrown.
mapProjection is null http://path_to_library/OpenLayers.js?lwx9io Line 1570
The kml is requested first time around but nothing gets displayed. If I zoom the map to cause the kml to be re-fetched then the markers are displayed as expected.
It makes no difference whether I host the Openlayers library locally or fetch it remotely.
I can switch to 2.10 and there is no error, but not sure if that is causing some other issues.

I attached a faulty KML file.

Anonymous (not verified) CreditAttribution: Anonymous commentedAs mentioned in #1817400: Add baselayers first, this is to do with a change in the implementation of the Fixed strategy when merging features into a layer. The map projection is required, but doesn't exist at the point of adding some layers.
The fix in that issue seems to also resolve this issue.

PolThis should be fixed now, see #1817400: Add baselayers first.
