Hi,
My situation:
- 1 Tree component (id=tree)
- 1 XMLListCollection as a dataprovider for the tree (id=treeData)
- 1 String, a url, that has to be found & selected.
My XMLListCollection looks like this:
<page title="page1" href="url1">
<page title="subpage1" href="url2"/>
<page title="subpage2" href="url3">
<page title="subsubpage1" href="url4">
</page>
</page>
<page title="page2" href="url5">
<page .../>
<page .../>
</page>
Etc. All nodes are named 'page' and have a href property.
What I need now, is a way to select the node in the tree for the given url. For
example, all nodes are collapsed and I want to select the node with href=url4.
How can I do this?
This is what I tried:
var t:XMLListCollection = this.treeData;
var url:String = "myURL";
for(var i:Number = 0; i<t.length; i++)
{
//this works, nodes now contains a list of xml items with the correct
url.
var nodes:XMLList = t[i]..page.(@href==url);
if(nodes.length() > 0)
{
//I only want to select the first occurence
tree.selectedItem = nodes[0];
break;
}
}
This, however, gives me a weird error (probably not that helpfull):
TypeError: Error #1010: A term is undefined and has no properties.
