Try running .updateControl() on the tree
in question and see if that helps with redrawing. I know that (apparently
undocumented) method worked for me in the MX04 v2 components. I found
that by digging through the MX04 v2 components source.
My guess is it’ll probably work (at
least in 1.5 – 2.0 looks like it might be a big rewrite).
Maybe someone else knows a better way to
accomplish that.
Hope that helps/works,
Jeff

One step further…that code snippet *is* working…the dataprovider for the
tree is changed…the nodes *are*
removed…I believe it’s the tree component that’s not
refreshing properly. I’ve tried redraw and broadcasting modelChanged,
change events to no avail…

Tried this variation, same
result…removes a folders child nodes but leaves the
folder…don’t get it !!
var dp =
view.profileFields.dataProvider;
for (var locNode :XMLNode = dp.firstChild;
locNode != null;)
{
var exclude :Boolean = false;
if ( locNode.toString() ==
nodes[0].toString() )
{
trace("TRUE");
exclude = true;
}
var nextNode = locNode.nextSibling;
if( exclude )
{
locNode.removeNode();
}
locNode =
nextNode;
}

Subject: [flexcoders] Can't Seem
to removeNode properly from a Tree!
I'm attempting to loop through childNodes on a
tree dataprovider and
delete the currently selected node in that tree.
The tree's structure is fixed in that there is a
series of child
elements in which each child may be one level
deep.
When I execute the code below on an item off the
root, its children are
deleted but the folder itself remains ??
Also, if it is a leaf I'm deleting it magically
gets moved to the root
of the tree, yet is not deleted??
I must be missing something obvious here...any
help would be much
obliged!
In the code snippet below, sections is the array
of childnodes off the
root.
// Loop over sections
for(var i:Number=0; i<sections.length; i++)
{
trace("step2");
var fields =
sections[i].childNodes;
if( nodes[x] != sections[i]
)
{
trace("step3");
// Loop over fields
for(var y:Number=0; y<fields.length; y++)
{
trace("step4");
if( nodes[x] ==
fields[y] )
{
trace("step6: delete field");
var field :XMLNode = fields[y];
field.removeNode(); // Remove field
break;
}
}
} else {
trace("step5: delete section");
// Delete section
sections[i].removeNode();
break;
}
}
