Body
I have a custom login component in Flex that is a simple form that dispatches a custom LoginEvent when a user click the login button: <pre><code> <?xml version="1.0" encoding="utf-8"?> <mx:Form xmlns:mx="http://www.adobe.com/2006/mxml" defaultButton="{btnLogin}"> <mx:Metadata> [Event(name="login",tpye="events.LoginEvent")] </mx:Metadata> <mx:Script> import events.LoginEvent; private function _loginEventTrigger():void { var t:LoginEvent = new LoginEvent( LoginEvent.LOGIN, txtUsername.text, txtPassword.text); dispatchEvent(t); } </mx:Script> <mx:FormItem label="username:"> <mx:TextInput id="txtUsername" color="black" /> </mx:FormItem> <mx:FormItem label="password:"> <mx:TextInput id="txtPassword" displayAsPassword="true" /> </mx:FormItem> <mx:FormItem> <mx:Button id="btnLogin" label="login" cornerRadius="0" click="_loginEventTrigger()" /> </mx:FormItem> </mx:Form> </code></pre> I then have a main.mxml file that contains the flex application, I add my component to the application without any problem: <pre><code> <custom:login_form id="cLogin" /> </code> </pre> I then try to wire up my event in actionscript: <pre> <code> import events.LoginEvent; cLogin.addEventListener(LoginEvent.LOGIN,_handler); private function _handler(event:LoginEvent):void { mx.controls.Alert.show("logging in..."); } </code> </pre> Everything looks good to me, but when I compile I get an "error of undefined property cLogin...clearly I have my control with the id "cLogin" but I can't seem to get a"handle to it"...what am I doing wrong? Thanks.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
