Hi Lukas,
Thank you very much for your help. It works great for me using
var layers= new $wnd.Array();
though you're right and it works properly in Chrome but no in FF4. I'was making some tests and no way...
As it's a problem that I also have to face if I found any workaround I'll write you and please if you find it, let me know.
Cheers,
Alex.

Asunto: SV: Select feature in multiple layer
I've been banging my head against the same problem for quite some time.
I think that the problem is related to
var selectControl = new $wnd.OpenLayers.Control.SelectFeature(
[vectors1, vectors2], ....
Where you create an array with just []. I think that Alexander Solovets might be able to explain this better but it has to do with the context where the array is created. For it to exist in the webbpages' window (as in a plain javascriptapplication) you need to do:
Array = new $wnd.Array() and the populate this array.
I am not sure if $wnd.[] would work but I doubt it.
That said I have tracked my own problems (arrays not working properly in firefox 4) to the same line of code where you are (creating the SelectFeature) and I haven't yet got it to work.

Hi again,
I'm trying to solve the multilayer issue using JSNI calling the function above:
public static native void selectableAllLayers(JSObject map) /*-{
var vectors1 = new $wnd.OpenLayers.Layer.Vector("Vector Layer 1", {
styleMap: new $wnd.OpenLayers.StyleMap({
"default": new $wnd.OpenLayers.Style($wnd.OpenLayers.Util.applyDefaults({
graphicOpacity: 1,
rotation: -45,
pointRadius: 10
}, $wnd.OpenLayers.Feature.Vector.style["default"])),
"select": new $wnd.OpenLayers.Style({
})
})
});
var vectors2 = new $wnd.OpenLayers.Layer.Vector("Vector Layer 2", {
styleMap: new $wnd.OpenLayers.StyleMap({
"default": new $wnd.OpenLayers.Style($wnd.OpenLayers.Util.applyDefaults({
fillColor: "red",
strokeColor: "gray",
graphicName: "square",
rotation: 45,
pointRadius: 15
}, $wnd.OpenLayers.Feature.Vector.style["default"])),
"select": new $wnd.OpenLayers.Style($wnd.OpenLayers.Util.applyDefaults({
graphicName: "square",
rotation: 45,
pointRadius: 15
}, $wnd.OpenLayers.Feature.Vector.style["select"]))
})
});
map.addLayers([vectors1, vectors2]);
var selectControl = new $wnd.OpenLayers.Control.SelectFeature(
[vectors1, vectors2],
{
clickout: true, toggle: false,
multiple: false, hover: false,
toggleKey: "ctrlKey", // ctrl key removes from selection
multipleKey: "shiftKey" // shift key adds to selection
}
);
map.addControl(selectControl);
selectControl.activate();
}-*/;
But I received the next error:
"(TypeError): Object [object Object],[object Object] has no method 'getZIndex' stack: TypeError: Object [object Object],[object Object] has no method 'getZIndex' at Object.moveLayerToTop (http://myurl) at Object.activate (http://myurl) at Object.activate (myurl) at ..."
The thing is if I change the code and write SelectFeature for just one layer, it works:
var selectControl = new $wnd.OpenLayers.Control.SelectFeature(vectors1, {....
but using an array doesn't work, Please, does anyone know what's the problem?
Thanks in advance,
Alex.

Asunto: [Gwt-openlayers-users] Select feature in multiple layer
Hi all,
I'm trying to enable Select feature in multiple layers at the same time. I tried to extend SelectFeatureImpl adding the method:
public static native JSObject create(JSObject layer1, JSObject layer2, JSObject options)/*-{
return new $wnd.OpenLayers.Control.SelectFeature([layer1, layer2], options);
}-*/;
but it doesn't work.
Any one know how to handle this?
Thank in advance,
Alex.
