[GitHub] [royale-asjs] brianraymes opened a new pull request #887: ArrayListView: Dispatch lengthChanged binding event if necessary after a refresh

brianraymes opened a new pull request #887:
URL: https://github.com/apache/royale-asjs/pull/887


   ArrayListView does not dispatch a "lengthChanged" event after performing a refresh which can alter the length from a filter.
   
   **Steps to Reproduce**
   
   1. _Create a bindable ArrayListView_
   
   ```
   [Bindable]
   public var names:ArrayListView = new ArrayListView(new ArrayList(["A", "B", "C"]));
   ```
   
   2. _Bind something to the length property_
   
   ```
   <j:Label text="Length: {names.length}"/>
   ```
   
   3. _Add a filter and refresh_
   
   ```
   names.filterFunction = filterFunctionThatRemovesB;
   names.refresh();
   ```
   
   **Expected Results**
   
   Label is updated from `Length: 3` to `Length: 2`.
   
   **Actual Results**
   
   Label is not updated and remains as `Length: 3`.
