[twinkle]

new Ext.tree.TreePanel({
                    rootVisible:true,
                    layout:'fit',           
                     loader: new Ext.tree.TreeLoader({
                        requestMethod: 'GET',
                        dataUrl:'XmlTreeLoader.json'                        
                    }),
                    root: new Ext.tree.AsyncTreeNode({
                        draggable:false,
                        text:langResStr_tasks
                    })
                })

Can anyone help me, why I could not get my tree nodes from JSON file?

Try adding a loadexception handler to the loader to see if the data loads correctly.

ps. XHR requires that XmlTreeLoader.json is served from a HTTP server. If XmlTreeLoader.json is a file on the local file system you need to include ext-basex.

[twinkle]

I tried showing my file and its total count shows '0'.
Also, I do not understand why I need ext-basex.

[Condor]

1. Are you testing local files or files on a webserver?
2. Did you get a 'load' event or a 'loadexception' event in the TreeLoader?

[twinkle]

I am using local file and I load it.
I did not take any exception.
Therefore,I did not include loadexception.
Is it necessary in this situation?

[Condor]

ExtJS can't load local files.

The ext-basex user extension adds support for loading local files.

[twinkle]

I include this but nothing change.
Once I have load local data from json to
my gridpanel but I could not achieve for treepanel.
This is confused my mind. Nobody has any example
which includes json and treepanel? and also treepanel
take nodes and leaves from json.
Please..

Are you including ext-basex-min.js after ext-all.js in your HTML?

[twinkle]

Yes, but nothing has changed
