Hi Jon, Event bubbling exists specifically for display objects. It is generally used for events like mouse clicks and keyboard presses. A limited subset of Flex events bubble so that they can be intercepted all the way up the display list.
There is some good documentation on this at the link below: http://livedocs.macromedia.com/labs/1/flex20beta3/wwhelp/wwhimpl/common/ html/wwhelp.htm?context=LiveDocs_Parts&file=00000475.html If you really need bubbling, then you will need to put your object on the display list. Alternatively you can use a solution that doesn't require bubbling. The simplest solution would be to create your listener directly on your WebServiceCheck object. I've pasted a demo app that may be helpful. Create a new project, and place both files in the project's root directory. The project shows event capturing from instances of a custom class. CustomObject1 is not placed on the display list; customObject2 is placed on the display list in actionscript; and customObject3 is placed on the display list in MXML. When you run it you will see that bubbling up to the Application only happens for customObjects 2 and 3. Since customObject1 is not on the display list, the only way to receive events dispatched from it is to create an event listener directly on the object. Note that I have used UIComponent as the base class for my custom class rather than Sprite because it is more compatible with the other flex classes. If you are creating objects that dispatch events but do not use bubbling, then you do not need to descend from UIComponent. For example, Validator descends directly from EventDispatcher.
