Question

I am testing my ExtJs App with Jasmine. So there are no views involved.

I want to expand several nodes, but first my root node. But even expanding that node fails.

I create my TreeStore, then:

Code:

// oStore is my treestore, everything OK
// Here, I also tried calling oStore.load(); see below

var oNode = oStore.getNodeById( 'root' );

// oNode.isExpanded() says false
// oNode.hasChildNodes() says false

oNode.expand(false, function(oChildren) {
    // it never gets here
    console.log( "hello?");
});

My listener for load gets called, but the listener for beforeexpand does not get called.

If I call oStore.load() at the beginning after store creation, then when the on load listener gets called it says, oNode.childNodes.length has 3 children…

1. So why is expand()‘s callback not called? How can I get that node to expand?

2. Why are the children of the node already loaded when calling oStore.load()? After that expand() is also not fired.

---

EDIT:

Starting my root node with expanded: true makes my store collapse correctly on collapse(), but after it expand() does nothing.

oNode.collapse(false, function() {
   console.log( "collapse()" ); // works, but expand() afterwards does not
});

Found the solution. I need to wait for the store to get loaded. Is is a Jasmine issue:

runs( function() {
         oStore.on( 'load', function() {
            bStoreLoaded = true;
         });
      });

waitsFor( function() {
         return bStoreLoaded; 
      }, " store to be loaded", 5000 );

runs( function() {
         oNode.expand(false, function( aoChildren ) {
            aoChildrenRoot = aoChildren;
            bRootExpanded = true;
         });
      });
