Package	mx.data
Class	public class Conflicts
Inheritance	Conflicts ArrayList EventDispatcher Object

Language Version:

ActionScript 3.0

Product Version:

LiveCycle Data Services for Java EE 3

Runtime Versions:

Flash Player 9, AIR 1.1

The Conflicts class represents a list of conflicts. When conflicts are detected between changes made by a client and those made on the server, a Conflict object is created for each item which contains both the client and server versions of the data involved in that item at any given time.

You cannot commit any changes until all conflicts are resolved. At that point, the DataService.commit() method will call remove all of these conflicts. If you attempt to resolve a Conflict which was already resolved, an error is thrown.

An instance of this class can be accessed from the DataService.conflicts property.

Because this class implements IList it can be used with an ArrayCollection.list property, allowing it to participate as a data source for user interface controls and data binding.

Indicates if there are any unresolved conflicts in the list. When this returns true all conflicts have been resolved and DataService.commit() can be called without an error.

This property can be used as the source for data binding. When this property is modified, it dispatches the propertyChange event.

Implementation
public function get resolved():Boolean

This is a convenience method that iterates all of the conflicts within this list and invokes the Conflict.acceptClient() method. Once completed this method will clear all of the conflicts in the list. Calling this method will requeue each local change and update all property values such that a subsequent call to DataService.commit() should succeed, allowing these changes to override the current ones.
