Hi all,
I have upgraded to the latest version of Openlayers 2.10 and for some
reason my GeoExt Tree Nodes layers are not visible when turned on.
However, when I click on the map for WMSGetFeatureInfo even if the
layers are not visible, I get the correct feature attributes results
back in a popup. No errors as well. I have not changed anything in my
application. I am using GeoExt version 0.7. However, with the previous
version of Openlayers 2.9
GeoExt Tree nodes code below;
/* --------------------------------------------------------------
* Treeview
* -------------------------------------------------------------- */
function hackneylayertree() {
var LayerNodeUI = Ext.extend(
GeoExt.tree.LayerNodeUI, new GeoExt.tree.RadioButtonMixin()
);
// configuration for editing it in the UI
var treeConfig = [
{
nodeType: "gx_baselayercontainer",
text: "Baselayer",
leaf: false,
expanded: boltreeExpand
},
/* --------------------------------------------------------------
* Overlays
* -------------------------------------------------------------- */
{
text: "Overlays",
expanded: true,
children: [{
nodeType: 'gx_layer',
layer: "Hackney Parks",

'REQUEST=GetLegendGraphic&VERSION=1.0.0&FORMAT=image/png&WIDTH=' +
iconWidth + '&HEIGHT=' + iconHeight + '&LAYER=Hackney Parks'
},
{

'REQUEST=GetLegendGraphic&VERSION=1.0.0&FORMAT=image/png&WIDTH=' +
iconWidth + '&HEIGHT=' + iconHeight + '&LAYER=Water Regions',
qtip: qtipTooltip
}]
},
/* --------------------------------------------------------------

}];
/*Layer Tree*/
//===================================================================
// create the tree with the configuration from above
var tree = new Ext.tree.TreePanel({

loaders
// of nodes further down the tree hierarchy
applyLoader: false,
uiProviders: {
"layernodeui": LayerNodeUI
}
}),
root: {
text: "Hackney Map Layers",
nodeType: "async",
children: treeConfig
},
rootVisible: true,

});
tree.getRootNode().expand();
}
Any help or suggestions would be appreciated.
Thank you.
