[OpenLayers-Users] WMS overlay disappearing with Google Maps v.3

[Dalton Filho]

Thank you Gery and Phil!

Passing the Google projection on the constructor options fixed the issue.
Something as simple as:

    var options = {
        projection: "EPSG:900913"
    };

    map = new OpenLayers.Map('map', options);

made all the difference: now maxExtent has a utm value as it should and WMS
overlay is rendered in all zoom levels.

Last note: it believe it wouldn't hurt if openlayers examples that use
google maps made use of this projection parameter too since this is
required...
