Add node on a treepanel with direct proxy

[xmart2k]

Hello,

I have a tree that is loading data with direct.
My proxy is defined like this

proxy: {        type: 'direct',
        api : {
            read: data.readNodes,
            create: data.createNode

        },
        reader: {
            type:'json',
            root: 'data'
        }
        
    },

I've managed to create a node for this tree with appendChild. My question is, how can I send to the server the new created node? so basically I want to send a request to createNode with details for the new node. Or maybe update the treestore?

Thanks!

When a non-left node is expanded, it should send a request with that node so you can load it's children.

Thanks for the response, but after I've read it, I understand that I was not very clear on what I want.
My problem was that after adding the node, in client side, in the tree, I don't know how will a send the info to the server, to add it into the database.

I've done some digging and found that after append, the node is added to the store and then probably I should use the store.sync(). But after I call the sync method i'm having an error: "fn is undefined". The error is in the method doRequest from the class Ext.data.proxy.Direct. Don't know why "if (operation.action == 'read')" is true, I was expecting to go on create.

Thanks!

So you add a node and call store.sync(). In your store's proxy, do you have the api setup so that the create is matched to a direct function?

yeap, this is my proxy

proxy: {        type: 'direct',
        api : {
            read: dataProvider.model.ProtectedEntitiesEPS.getADGroups,
            create: dataProvider.model.ProtectedEntitiesEPS.addNode
        },
        reader: {
            type:'json',
            root: 'data'
        }
        
    },

It's telling me that addNode isn't resolvable. What happens when you type that function into the console?

I'm getting this error: "TypeError: fn is undefined"
this is the code for the add method:

var tree = Ext.getCmp("myTree");var selectedNode = tree.getSelectionModel().getLastSelected(); 
var newNode = {};
            
            newNode.text = "testNode";
            newNode.type = 275;


            
            var appNode = selectedNode.appendChild(newNode);


var rec = tree.getStore().getUpdatedRecords();
tree.getStore().sync();

ok, found my problem...the function for create was wrong.

now the request is pointing to the create method, correctly, but at the server side I don't get any data from that node.

[xmart2k]

solved it...my mistake, I was pointing to another function
