If I choose one of the Google layers, no map is displayed, and I see the error: Error during map rendering: TypeError: this.projection.getUnits is not a function
I followed the tutorial, and with the 'OSM Mapnik:' layer it worked fine. But changing to any Google layer I get the error message above. (I've been using the GMAP module for several years, and so wanted the end result from OpenLayers to look as similar as possible to the current maps on our site)
Clearing site cache didn't help.
The error happens during the call to Drupal.openlayers.addLayers(map, openlayers); in openlayers.js
I started with the Alpha7 release and had this problem. I've just upgraded to the latest dev release and still have the same problem.
Hopefully I'm missing something simple.
Although the module still has its rough edges, it all fits together in a logical way. Good work, and I look forward to making the switch.
