<pre wrap="">Hi,
I saw an earlier post that recommended using the opacity property to
access the opacity value of a layer; however, on my OpenLayers.Layer.WMS
layers, the opacity property always contains a null value. Any suggestions?

Thanks for the reply. Yes, I have called layer.setOpacity before
reading the opacity property. This changes the opacity as advertised.
But, I don't know how to get the value back out.<br>
<br>
I'm making an opacity slider control. I need to know the opacity of a
layer so I can set the slider value correctly.<br>

Cheers,<br>
