Filtering a Nested List

[English]

This should be a quick question: When filtering the store from which a nested list gets its data, should the nested list update automatically? I can't see any kind of refresh, or reload function.

I'm simply filtering some JSON with the code below. I can see that the data is being filtered, but the nested list doesn't alter.

            AllCoursesButton: {
                tap: function(button){
                    if(button.getIconCls()=='docs2')
                    {
                        button.setIconCls('doc');
                        button.setText('Mobile Courses');
                        var ActiveStore=this.getCatalogList().getStore();
                        //debugger;
                        ActiveStore.filter('nametxt', 'Mobile Courses');
                        console.log(ActiveStore.getData().length);
                        //ActiveStore.load();
                    }
                    else
                    {
                        button.setIconCls('docs2');
                        button.setText('All Courses');
                        var ActiveStore=this.getCatalogList().getStore();
                        ActiveStore.clearFilter();
                        console.log(ActiveStore.getData().length);
                        //ActiveStore.load();
                    }
                }
            }

The NestedList uses TreeStore but each child List uses a Node store so you can filter the Node store on the list for the node. It's not the simplest for the TreeStore.

Thanks, Mitchell. I'm not sure I understand your answer fully, but, I have just iterated through the node list for the nested list, and removed the items that I want to filter out.

I have tested (by using "eachChild"), and the node is definitely gone. Yet, there it still sits in the nested list.

It seems that nothing I do to either the nested list, or the underlying data, has any effect on the items displayed in the nested list once it has been displayed.

As the documentation is woefully inadequate, I am at a loss. How does one in any way manipulate the items displayed in a nested list, once that list has been displayed?

Oh well. As Sencha provides no usable documentation, and I can find nothing on the Internet, I'm having to treat the nested list as a dumb component, and simply filtering at the back-end with a parameter to the AJAX call.
