I'm taking a layer (layer_orig) and calling the clone method to create a new layer (layer_clone) with same features, styles, etc. I am changing the name and map instance of the layer with:

layer_clone.map = null;
layer_clone.setName(name);

This works exactly as expected, even giving a unique layer id to the new layer.

However, if I then update the styleMap of layer_clone, the styleMap of layer_orig is updated as well - suggesting that layer_clone is a reference to layer_orig and not a completely unique Layer object.

Is there a way to get a unique Layer object that is a direct clone of another layer?

I have in mind to use cloning in the next few days, i ll let you know what i end up with. – U2ros Oct 9 '12 at 17:50
That's be helpful! I look forward to hearing from you! Thanks! – swatkins Oct 9 '12 at 18:33
have you tried cloning the stylemap also? – CaptDragon Oct 9 '12 at 19:09
No, I hadn't. I just did clone the OpenLayers.Style object (OpenLayers.StyleMap doesn't have a clone method) - and it worked. @CaptDragon - add this as an answer and I'll mark it as the accepted answer! Thanks for the help! – swatkins Oct 9 '12 at 19:26
@swatkins: roger that! – CaptDragon Oct 9 '12 at 19:28

have you tried cloning the Style object seperately? :)

Could you please provide the syntax for how to clone an existing layers style? Thanks – Todd Krueger Jan 10 at 17:33
it's feature.style.clone(); I know you're getting undefined for this. Check what is undefined. Is it feature.style? – CaptDragon Jan 10 at 18:08
