Question

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 ?

Answer 1

TreeStore haven’t methods like Store.add or Store.delete. Because it needs information of parent node. So, example for add child to root element:

var root = me.getCategoryTree().getRootNode();
root.appendChild( rec );

me.getCategoryTree().getStore().sync();
