Issue with Flex 3 error "class is not an IEventDispatcher"
I just started playing around with Flex 3 for a project at work. Part of the project requires pulling customer site information and displaying on a Google Map. I figured out how to do that, but when I would display grid data I would get the warning.
warning: unable to bind to property ‘xxx’ on class ‘xxx’ (class is not an IEventDispatcher)
After a few Google searches, I found an easy solution and a “d’uh moment”.
I had set up my data structures as ActionScript Class files.
package
{
public class Site
{
public var site_id:int;
public var name:String;
public var street_address:String;
public var city:String;
public var state:String;
public var zip:String;
public var latitude:Number;
public var longitude:Number;
public function Site(obj:Object = null)
{
if (obj != null)
{
this.site_id = obj.site_id;
this.name = obj.name;
this.street_address = obj.street_address;
this.city = obj.city;
this.state = obj.state;
this.zip = obj.zip;
this.latitude = obj.latitude;
this.longitude = obj.longitude;
}
}
}
}
When ever I made a web service request to retrieve the site data, I would get the warning message. A simple fix to not get the warning was to simply bind each of the variables.
package
{
public class Site
{
[Bindable]
public var site_id:int;
[Bindable]
public var name:String;
[Bindable]
public var street_address:String;
[Bindable]
public var city:String;
[Bindable]
public var state:String;
[Bindable]
public var zip:String;
[Bindable]
public var latitude:Number;
[Bindable]
public var longitude:Number;
public function Site(obj:Object = null)
{
if (obj != null)
{
this.site_id = obj.site_id;
this.name = obj.name;
this.street_address = obj.street_address;
this.city = obj.city;
this.state = obj.state;
this.zip = obj.zip;
this.latitude = obj.latitude;
this.longitude = obj.longitude;
}
}
}
}
That was simple enough. Took me an hour or so of search to figure it out.
