getFeatureInfo for the active Layer

[Emilio Otero]

Hi everyone,

how  can I get a getFeatureInfo for an active Layer? I use the GeoExt.plugins.TreeNodeRadioButton. This is my GetFeatureInfo:

infoControl = new OpenLayers.Control.WMSGetFeatureInfo({

url: 'MyURL',

queryVisible:true,

maxFeatures: 50,

layers: [layer1, layer2, layer3, layer4],

});

infoControl.events.register("getfeatureinfo",this,showInfo);

mapPanel.map.addControl(infoControl);

infoControl.activate();

function showInfo(evt){

windowInfo.show();

$('MyDIV').innerHTML = evt.text;

}

When I click in the radioButton the layer is activated, but I recive the response from the visible layers.

For example, I have a Layer with all the information, I make diferents Postgress views with this Layer, if I make visible the diferents Layers in the view, and if I make active one layer, I recive the getFeatureInfo about two Layers (or more), and I want to recive about the active Layer.

How can I do it?

thanks!
