Extjs Tree Store auto sync with server

[charles.bourasseau]

Hi,

how to use store to sync with server when using a Tree ?

I tried to use TreeStore but it does not have any appendChild oder addChild.
NodeInterface has a appendChild method but it does not sync with the server trough the store or proxy...

Any ideas ?

1. You add records into TreeStore through its nodes. The following example shows how to add a node into root node.

treestore.getRootNode().appendChild({text: 'node', leaf: true....});

2. To sync TreeStore to with server, you use treestore.sync() or set its autoSync to true to automatically sync.

It works actually very well.

I just have a problem because the autoSync does not work even though it's set to true...

var store = Ext.getStore('MyStore');
store.getNodeById(id).remove(); // No Ajax here
store.sync(); // Ajax..

I also tried destroy(), but it produces an error and I can't figure out which line produces it:

TypeError: Cannot call method 'indexOf' of undefined

Below is my fix in removing a node.

var store = Ext.getStore('MyStore');
// store.getNodeById(id).remove(); // No Ajax here
var node = store.getNodeById(id);
node.parentNode.removeChild(node);
store.sync(); // Ajax..

I works, but it's not autoSync

I would like to have autoSync

Which version do you use? TreeStore.autoSync has effect only from Ext 4.1.
