dijit.tree.ForestStoreModel throws error on newItem

[rjones]

If a dijit.tree.ForestStoreModel? is created with an store with 0 items an error is thrown during the store.newItem process because dijit.tree.ForestStoreModel?._requeryTop does not check to make sure that the root has children. One workaround is to extend dijit.tree.ForestStoreModel? and extend the _requeryTop function:

dojo.declare("dijit.tree.WorkingForestStoreModel?", [dijit.tree.ForestStoreModel?], {

/**

• dijit.tree.ForestStoreModel? has a bug that presents when you create
• a model with an empty store and call newItem an error occurs because
• the root has no children and there was no null check.
• @Override */

_requeryTop: function(){

if ( this.root.children ) {

this.constructor.superclass._requeryTop.apply(this);

}

}

});

It works for me. I'm attaching the test case I used.

In the future, after creating a ticket, you need to attach full test cases using the Attach File button.

Despite already being fixed, attaching best test example. Whith ability to show patch by using dijit.tree.WorkingForestStoreModel? from ticket description.
