Any suggestions? layer.opacity is representative of the clientside opacity; did you assign the opacity using setOpacity or similar? 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. I'm making an opacity slider control.  I need to know the opacity of a layer so I can set the slider value correctly.
