[OpenLayers-Users] mr. OL, don't create the hidden layer tiles, please!

[Pere Roca Ristol]

hi all,
I want to emulate LayerSwitcher actions of hide/show Base layers. I want to
do it from another radio form.

When user clicks Background layer A, layer B is hidden, and if user zooms, B
tiles should NOT be created (I see them in Firebug) to increase performance.
My problem is that these tiles are created even if I use
setVisibility(false) for layer B (it does not happens using LayerSwitcher
buttons).

I tyried to map.removeLayer(B), and Ok, B tiles are not created anymore. But
later, when user chooses B (map.addLayer(B)) and zoom in/out... layer B bbox
parameters are not updated and is allways the same B image.

some idea?
thanks!

Pere
