Hi all,<br>
<br>
until now I only used OpenLayers and GeoExt with the experience
gained from several tutoials ;)<br>
I created MapPanels and LayerTrees like this...<br>
<pre><span class="nx">root</span><span class="o">:</span> <span class="k">new</span> <span class="nx">GeoExt</span><span class="p">.</span><span class="nx">tree</span><span class="p">.</span><span class="nx">LayerContainer</span><span class="p">({</span>
<span class="nx">layerStore</span><span class="o">:</span> <span class="nx">mapPanel</span><span class="p">.</span><span class="nx">layers</span><span class="p">,</span>
<span class="nx">expanded</span><span class="o">:</span> <span class="kc">true</span>
<span class="p">}),
</span></pre>
<br>
Now I tried to define a customized layerlist with sublayers and make
them visible in map onClick:<br>
<br>
<pre>var layerList =[{ </pre>
<pre> "text":"Land use",</pre>
<pre> "children":[{</pre>
<pre> "nodeType":"gx_layer",</pre>
<pre> "layer":"wms"</pre>
<pre> },{</pre>
<pre> "nodeType":"gx_layer",</pre>
<pre> "layer":"MAS"</pre>
<pre> },{</pre>
<pre> "nodeType":"gx_layer",</pre>
<pre> "layer":"MRS"</pre>
<pre> }] </pre>
<pre> },{</pre>
<pre> "text":"Air quality and health",</pre>
<pre> "children":[{</pre>
<pre> "nodeType":"gx_layer",</pre>
<pre> "layer":"wms2"</pre>
<pre> },{</pre>
<pre> "nodeType":"gx_layer",</pre>
<pre> "layer":"GMAS"</pre>
<pre> },{</pre>
<pre> "nodeType":"gx_layer",</pre>
<pre> "layer":"MRS"</pre>
<pre> }] </pre>
<pre> }] ;
var tree = new Ext.tree.TreePanel({
region: 'west',
title: "Layers",
width: 200,
autoScroll: true,
enableDD: true,
lines: false,
loader: new Ext.tree.TreeLoader({
applyLoader: false
}),
root: {
children: layerList
},
rootVisible: true
});
</pre>
But only <i>root</i> and the first node are visible in LayerTree.
The nodes are not expandable. <br>
What is missing in this definition?<br>
<br>
The error message in Firebug shows:<br>
<span role="presentation" class="objectBox objectBox-errorMessage
hasBreakSwitch ">this.node.layer.getVisibility is not a function</span><br>
<br>
<br>
Best regards,<br>
