RE: [flexcoders] adding an event listener to a dynamically added component

Try:

var newRow:SearchInputRow = new SearchInputRow();

newRow.addEventListener("onRemoveRow",myEventHandler);

searchRows.addChild(newRow);

Subject: [flexcoders] adding an event listener to a dynamically added
component

 

I have a search component that allows the user to add new search
criteria on the fly. 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? 


Thanks in advance,

Rob
