[OpenLayers-Users] OL 2.11 problem with TileCache overlays on Google v2 base layer

[Derek Watling]

I have been using OpenLayers since 2.07 and am currently using 2.10. This
morning I downloaded 2.11 changed the references to the .css and .js files
and ran a test.

I have a TileCache base layer and a number of TileCache overlays, together
with the option of using Google base layers (API v2). After pointing to the
OL 2.11 code my overlays display "pink tiles" when one of the Google base
layers is selected.

On closer inspection I see that the calls to my own tiles are something
like:
http://cache.cmatile.co.za/CMCStreetNumbers/-1/000/000/432/000/000/413.png
with the zoom level becoming "-1"!

I have tested in IE 9 and Firefox 6 with the same result.

The current working version using OL 2.10 can be viewed at

Below is the relevant code from the page:

// My base layer
cmaBase = new OpenLayers.Layer.TileCache(
