Called when any of the contained items in the list dispatch an ObjectChange event. Wraps it in a CollectionEventKind. Parameters item : Object — Object reference to the item that should be removed. Remove the item at the specified index and return it. Any items that were after this index are now one index earlier. Parameters index : int — The index from which to remove the item. Place the item at the specified index. If an item was already at that index the new item will replace it and it will be returned.
Parameters item : Object — the new value for the index index : int — the index at which to place the item. If the item is an IEventDispatcher, watch it for updates. This method is called by the addItemAt method, and when the source is initially assigned. Parameters item : Object — The item passed to the addItemAt method. If the item is an IEventDispatcher, stop watching it for updates.
This method is called by the removeItemAt and removeAll methods, and before a new source is assigned. Parameters item : Object — The item passed to the removeItemAt method. The properties of the event object have the following values. Not all properties are meaningful for all kinds of events. See the detailed property descriptions for more information. Filters: Retrieving Data from Server Retrieving Data from Server Classes x. Package mx. Items in the backing Array can be accessed and manipulated using the methods and properties of the IList interface.
Operations on an ArrayList instance modify the data source; for example, if you use the removeItemAt method on an ArrayList, you remove the item from the underlying Array.
This base class will not throw ItemPendingErrors but it is possible that a subclass might.

Equivalent to addItemAt item, length. Parameters item : Object — The item to add. Adds the item at the specified index. The index of any item greater than the index of the added item is increased by one. If the the specified index is less than zero or greater than the length of the list, a RangeError is thrown. Parameters item : Object — The item to place at the index. Returns whether the view contains the specified object. Unlike the IViewCursor. If the view has a filter applied to it this method may return false even if the underlying collection does contain the item.
Parameters item : Object — The object to look for. Prevents changes to the collection itself and items within the collection from being dispatched by the view. Also prevents the view from updating the positions of items if the positions change in the collection. The changes will be queued and dispatched appropriately after enableAutoUpdate is called. If more events than updates to a single item occur, the view may end up resetting.
The disableAutoUpdate method acts cumulatively; the same number of calls to enableAutoUpdate are required for the view to dispatch events and refresh. Note that disableAutoUpdate only affects the individual view; edits may be detected on an individual basis by other views. Dispatches an event into the event flow. The event target is the EventDispatcher object upon which dispatchEvent is called. Parameters event : Event — The event object dispatched into the event flow.
Enables auto-updating. See disableAutoUpdate for more information. Parameters index : int — The index in the list from which to retrieve the item. Note: unlike IViewCursor. Parameters item : Object — The item to find. Checks whether the EventDispatcher object has any listeners registered for a specific type of event. This allows you to determine where an EventDispatcher object has altered handling of an event type in the event flow hierarchy.
To determine whether a specific event type will actually trigger an event listener, use IEventDispatcher. The difference between hasEventListener and willTrigger is that hasEventListener examines only the object to which it belongs, whereas willTrigger examines the entire event flow for the event specified by the type parameter.
Notifies the view that an item has been updated. This method is useful if the contents of the view do not implement IPropertyChangeNotifier. If the call to this method includes a property parameter, the view may be able to optimize its notification mechanism. Otherwise it may choose to simply refresh the whole view. Parameters item : Object — The item within the view that was updated. If property was null, this can be the old value of the item.
If property was null, there's no need to specify this as the item is assumed to be the new value. Applies the sort and filter to the view. The ICollectionView does not detect changes to a sort or filter automatically, so you must call the refresh method to update the view after setting the sort or filterFunction property. Returns true if the refresh was successful and false if the sort is not yet complete e. Removes a listener from the EventDispatcher object.
If there is no matching listener registered with the EventDispatcher object, a call to this method has no effect. If the listener was registered for both the capture phase and the target and bubbling phases, two calls to removeEventListener are required to remove both: one call with useCapture set to true , and another call with useCapture set to false.
Removes the item at the specified index and returns it. But now i want to do something like. Is there a solution? If i try it with the array, flexbuilder says he can't do databinding with akwArray[0] Stack Overflow for Teams — Collaborate and share knowledge with a private group.

Adds a list of items to the current list, placing them at the position index passed in to the function. Registers an event listener object with an EventDispatcher object so that the listener receives notification of an event.
