Hello GeoExt/ExtJS list, I am just having trouble with one thing after another. I have a layer that I create after my tree panel has been created ( I have my reasons, getting the map's extent of the viewport returns null if I try to use getExtent() before the viewport has been created and I need getExtent() as parameters to create this new layer. So what I have done is created a layerNode that I want to add to a container for this layer. However this node does not take the form of a radio button, which I believe it should, nor does it match up to serve functionality to toggle the layer on and off, instead it throws an error in firebug:
this.node.getOwnerTree() is null var checkedNodes = this.node.getOwnerTree().getChecked(); http://localhost:8080/geoserver/www/GeoExt/lib/GeoExt/widgets/tree/LayerNode.js Line 84 //function to create the original child overlay container with radio buttons function childContainerRadioButtons(text, layerStore, parent, iconCls){ parent.appendChild(new GeoExt.tree.OverlayLayerContainer({ text: text, layerStore: layerStore, expanded: true, iconCls: iconCls, //If not specified, defaults to original image loader:{ baseAttrs:{ checkedGroup: "foo" } } })); }//end childContainerRadioButtons //TreePanel code //Tree menu for layers var layerTree = new Ext.tree.TreePanel({ overflow: 'visible', // For the Combo popup region: "west", title: "Map Layers", root: layerRoot, loader: new Ext.tree.TreeLoader({applyLoader: false}), enableDD: true, collapsible: true, width: 300, autoScroll: true, expanded: false }); //The node I want to add to that child overlay container layerStore.loadData([vectorPano], true); //adding layer to the layerstore of that container var layerContainer = layerRoot.findChild('text', 'Photo Layers'); layerContainer.appendChild(new GeoExt.tree.LayerNode({ leaf: true, text: 'Panoramio Photos', layer: vectorPano, layerStore: layerStore, loader: {baseAttrs: {checkedGroup: "foo"}}, //This node is the odd one out, rendering a checkbox while it siblings are radio buttons checked: false })); I've been stuck for a while, any hints would be greatly appreciated. I thought I'd be able to get it on my own if I had the other issues resolved (asked recently) and I apologize for asking all the questions. I'm just having a hard time :-/ Thanks in advance for your continuous kind help :) elshae
