[1.1.1] Tree AsyncNodes and TreeNodes

[bemeall]

As I'm developing an application with extjs, i've got some issue now.

I've got a tree, loading his nodes with a treeloader from a php script providing json data.
Working perfectly well.

But now comes the problem, if I want to add a node to this tree manually, it doesn't work.
So on the tree loaded with the treeloader, i'm adding a normal TreeNode to the root node with the appendChild method. It doesn't work if I do both treeloader and manual. If I choose one of them, it works well.

I've tried both the treeloader on the treepanel and on the rootnode as well, I can't get the combination of both work together.

Maybe anyone had this issue before, or can give me a hint in the right direction?

Thanks!

Just tested it with the 2.0 tree example, has the same problem for me. Maybe it's by design and do I have to look foor a workaround?

Code is almost the same as the tree example (in this case with the treeloader on the root node, tried both):

Tree


var tree = new Tree.TreePanel('tree-div', {
animate:true,
enableDD:true,
rootVisible : false,
loader: new Tree.TreeLoader(),
containerScroll: true
});


Root node


var root = new Tree.AsyncTreeNode({
loader: new Tree.TreeLoader({
dataUrl:'index.php?action=gettree'
}),
text: 'Website',
draggable:false,
editable:false,
id:'source'
});


Extra TreeNode (the piece of code that doesn't work with a treeloader specified)


var node = new Tree.TreeNode({
text: 'test',
id: 'test'
});
root.appendChild(node);


Tree rendering


tree.setRootNode(root);
tree.render();
root.expand();

Still haven't found a solution for this problem :(
Tried some things, but haven't found things that made a difference.

Did some other things that work amazing, but i'm stuck on this one...

Im having similar issue, but im not using tree loader. I have a tree whihc is created when the page loads, then i want to add more nodes to existing tree as the user executes certain tasks. The append does nto seem to be adding the nodes to my tree.

oy guys,

I've extensively worked with the TreePanel and y'all need to wait for the Tree loader's loading event to end before adding in new nodes.


tree.loader.on("load"
// wait for the load function to be launched
, function () {
// get a reference of the tree's root node.
var rt = this.getRootNode();
// create the new node
var node = new Ext.tree.TreeNode( {text: 'test',id: 'test'} );
// append it to the current root node
rt.appendChild(node);
}, tree, true
);

Looks like it works for me! If I place the treeloader on the tree itself, it is.
Needs some finetuning, but I think I'll get there myself ;)

Thanks!
