If I click a radiobutton and click at my map than I get a response. If I change radiobutton/layer than I get a response from the new layer and from one before. <br><br>code of my tree panel:<br> id: 'panel',<br> title: 'Menu',<br> region: "east",<br> split: true,<br>
width: 200, <br> maxSize: 400,<br> collapsible: true,<br> collapseMode: "mini",<br> margins: '0 0 0 5',<br> layout: 'accordion',<br> layoutConfig: { animate: true},<br> items:
[{<br> title: "Layer tree",<br> width: 200, <br> id: "treelayer",<br> margins: '5 0 5 5',<br> xtype: "treepanel", <br>
loader: new Ext.tree.TreeLoader({<br> applyLoader: false}),<br> root: { nodeType: "async",<br> children: [ <br>

}, listeners: {"radiochange": function(node){getAttributes(node);}<br> },<br> rootVisible: false<br> }<br><br>and my code to get information:<br><br>function getAttributes(node) {<br><br> var name = node.layer.name;<br> var qlayer= node.layer.params.LAYERS;<br> var opt = node.layer.options;<br><br> var bbox=
node.layer.map.getExtent().toBBOX();<br> var breite = node.layer.map.size.w;<br> var hoehe = node.layer.map.size.h;<br><br> map.events.register('click', map, function (e) {<br> var url = node.layer.getFullRequestString({<br> REQUEST: "GetFeatureInfo",<br> SERVICE: 'WMS',<br> VERSION: '1.0.0',<br>

QUERY_LAYERS: [qlayer],<br> WIDTH: breite,<br> HEIGHT: hoehe});<br> OpenLayers.loadURL(url, '', this, setHTML);<br> OpenLayers.Event.stop(e);<br> });<br> function setHTML(response) {<br> //doesn`t work:<br> //map.addPopup(new GeoExt.Popup({html: response.responseText, map: map})); <br> alert(response.responseText);<br>
OpenLayers.Util.getElement('south').innerHTML = ""; <br> };<br>};<br><br>It seems that qlayers and/or QUERY_LAYERS were not deleted (is an array) after one request. Removing brakets [] did not help.<br>Any hints or tips about that?<br>Thanks for any comment.<br><br>Best regards<br>Sarah<br><br></div>
