Hi everybody and very good morning,

I have confused about the Alert components. I wonder why the Alert component should be import using

```auto

import mx.controls.Alert;

```

but why I cannot use

```auto

this.createObject("Button","cbtSubmit",this.getNextHighestDepth())

```

the Button components can use that but why not Alert component?

Can anyone tell to explain?
