Does this answer your question at all? “Creating a custom sort on a DataGrid control in Flex”

about sorting tree we can use @name for Sjoerd case?

I am receiving this document from a web service in e4x and initialize my xmllistcollection as follows:

My xml looks like:

Where member 3 is a child of member 2 and member 2 is a child of member 1. I have tried to apply the filter and the sort and nothing happens. Here are my methods:

protected function sortItems():void
{
	var treeSort:Sort = new Sort();

	treeSort.fields = [new SortField("@id", true)];
	dataSource_Tree.sort = treeSort;
	dataSource_Tree.refresh();
}
protected function filterByColor():void
{
	dataSource_Tree.filterFunction = colorFilter;  //dataSource_Tree is XMLListCollection
	dataSource_LOSTree.refresh();
}

protected function colorFilter(item:Object):Boolean   // User selects a color by textbox
{
	return item.@color == ‘blue’;
}

I have traced several times and each time nothing happens to the xml. no filter, no sort… nothing. According to the Flex documentation, filterfunctions are supposed to traverse the entire xml document node by node, but when i trace the passed in item on the colorFilter I get the entire xml document. And the colorFilter method only gets called once (with the full xml) instead of item by item.

Is there a different way I need to filter a tree with nested nodes?

Is that the entire XML that you want to sort, or is there more?

<test name="groupname">
    <test2 name="old">bla1data</test2>
    <test3 name="new">bla2data</test3>
</test>

What would the sortfunction look like?

private function sortXLC():void {
    var nameSort:Sort = new Sort();
    nameSort.fields = [new SortField("test.test2", true)]; // This wont work...

    factoryMethodsXLC.sort = nameSort;
    factoryMethodsXLC.refresh();
}
