Hello list, Questions about Layer.clone(): Is it supposed to work? I'm having major problems with it. My use-case is, I have a set of pre-defined layers in an included .js file, but I want users to be able to add multiple maps to a page, two or more of which may use the same layer. So, I'm trying to Layer.clone() a copy of each layer each time it gets put into a map. Couple of problems I've encountered so far:
1. It looks like the clone method is supposed to take either a null argument (which will return a clone of "this" layer), or a layer to clone. But, for example, if I call wmslayer.clone(), I get back an object with class = "OpenLayers.Layer", rather than "OpenLayers.Layer.WMS". This doesn't seem correct. 2. If I do something like this: wmslayerA = wmslayer.clone(wmslayer); wmslayerB = wmslayer.clone(wmslayer); then wmslayerA and wmslayerB have the same id...this doesn't seem right, and it seems to confuse the layer switchers for the two different maps...or something else is confusing them, because they're definitely confused. 3. The clone method is overridden in OpenLayers.Layer.Image , and it behaves differently--specifically, for a WMS layer wmslayer.clone(wmslayer) seems to work better, but for an Image layer imagelayer.clone() seems to work better...but it still doesn't work right. Shouldn't somelayer.clone() always be the same as somelayer.clone(somelayer)? or am I misunderstanding something? Is this supposed to work? Is it deprecated, or is there a better way to do it? Example of some of the above problems (especially #2) can be seen here: http://s89238293.onlinehome.us/w/index.php?title=Two_Maps . The site is using OpenLayers 2.6.
