[OpenLayers-Users] using more than one Layer.TileCache in a map?

[Eric Lemoine]

Hi

If you don't set isBaseLayer:false in the options passed to the
Layer.TileCache constructor then the layer is a base layer. If you
want the two TileCache layers to be active at the same time you must
send isBaseLayer:false to one of them. Also, note that
transparent:true has no effect as a Layer.TileCache option.

Cheers,

Eric
