How reload (refresh) one node in TreePanel?

tree.getLoader().dataUrl = url;

It doesn't work.

node.reload() reloads the children of the node, not the node itself.

You should try:

The 'node' it's my parent node:)
In my opinion, the note is reloading but tree store from url not....

I don't understand what you mean... Can you try to explain the problem better?

28 Sep 2009, 12:02 AM
ok, i will trying.
I think, the node is reloading, but the store in tree not...

28 Sep 2009, 12:08 AM
'store in tree'? Please explain...

My tree using store from url:
dataUrl: index.php...

I make some change on my node.

And refresh this url before reload node:
tree.getLoader().dataUrl = url;


The node is reloading, but with old data.

It should work (unless you specified a different loader for this node).

To make sure you should change:

node.getLoader().dataUrl = url;

28 Sep 2009, 3:12 AM
node.getLoader().dataUrl = url;

and "url" should be the same which in whole tree?

TreePanel support a global treeloader and/or a separate loader for every node.

If a node doesn't have a specific loader the tree loader will be used.

I don't know if you are using node specific loaders, so I simply suggested using the node loader just in case.

ps. If you are not using node specific loaders then this won't fix anything.

Ok, but how using node specific loaders? I'm using TreeLoader like this:

loader : new Ext.tree.TreeLoader(
dataUrl : file.php
uiProviders :
'col' : Ext.tree.ColumnNodeUI
and in file.php return json array with data.

You probably don't want to use node specific loaders - that is not the problem anyway.

There must be something else wrong (but I don't know what).

ok, so could you write me examples of code to refresh one node in treePanel?
I would be very grateful:)

I think, when I reload my node it is reloading but with old data store....
how can I refresh tree data store?

Have you found any solution to this, I am trying to achieve the same thing, but no luck.

I load all of the sub nodes (recursive) when I load the tree, maybe that is the reason, are you doing something similar?

I have changed the loading method, it now only loads the requested tree-nodes direct-children, and reloading a node seems to be working properly now, reload on leaf-nodes does not work (once a leaf, does not necesserily mean always a leaf).

Can anyone confirm if this are the expected behaviours or bugs?

Were you able to solve this?

I am also facing the same issue, my leaf node doesnt get reloaded, even after calling node.reload().
