[MapQuery] how to add an existing ol layer to mapquery

[Giuseppe De Marco]

You're right Volker,

it was a dummy examples,
I'm playng with a local WMS and now I'm in trouble with two things:

1. The layer initialize with 0 opacity
2. when map zoom change the ol_layer doesn't update 

I'm playing with:

        jQuery('#map').data("mapQuery").layers({
            type:'existing_ol',
            label:'example',
            legend:{url:'http://mapserver.edugis.nl/cgi-bin/mapserv?map=maps/edugis/cache/population.map&version=1.1.1&service=WMS&request=GetLegendGraphic&layer=Bevolkingsdichtheid_2010&format=image/png'},
            ol_layer:pcn_orto_06_sm_tlch,
            min_zoom:2,
            url:pcn_orto_06_sm_tlch.url,
            layers:pcn_orto_06_sm_tlch.params.LAYERS,
            });
        });

Hi Giuseppe,

where do you actually initialise the new layer? Is it already
initialised in ol_layer? It looks a bit strange that you use a WMS bit
have a Layer names osm.

Cheers,
