you can write your class that way, but then there is only one listener? ________________________________

The search criteria is contained in a custom component, one row per criteria. The first row is defined like this: <c:SearchInputRow onCriteriaChange="doCriteriaChanged(event)" removeButton="false"/> Rows can be added by clicking a button which dynamically adds a new component like so: var newRow:SearchInputRow = new SearchInputRow(); // add the new component to the VBox searchRows.addChild(newRow); The custom component has a button that can be used to remove any rows after the first row. The button calls a function that dispatches a custom event called onRowRemove private function doRemoveRow():void{ var e:Event = new Event("onRemoveRow",true); trace(e); dispatchEvent(e); } <mx:Metadata> [Event(name="onRemoveRow")] </mx:Metadata> The event fires, but my dynamically added rows never see it because they are not listening for it. How can I add an event listener for this custom event to my dynamically created components?
