>                 URL: https://issues.apache.org/jira/browse/FLEX-34913
>             Project: Apache Flex
>          Issue Type: Bug
>          Components: FalconJX
>    Affects Versions: Apache FalconJX 0.5.0
>            Reporter: Josh Tynjala
>            Assignee: Alex Harui
>             Fix For: Apache FalconJX 0.5.0
>
>
> Try the following ActionScript:
> class Example
> {
>     public var prop:Object = {};
> }
> var obj:Example = new Example();
> obj.prop.value = 5;
> var obj2:Example = new Example();
> trace(obj2.prop.value); //5
> The emitter puts the prop member on the prototype, so it is shared by all instances of Example:
> Example.prototype.prop = {};
> Instead, the emitter should set the property in Example's constructor so that each instance has a separate object. Maybe something like this:
> public function Example()
> {
>     this.prop = {};
>     super();
> }
> There is a workaround. A developer can manually set the property in the constructor, basically using the same code as above:
> class Example
> {
> 	public function Example()
> 	{
> 		this.prop = {};
> 	}
> 	public var prop:Object;
> }
