Call viewstack (main app) from component

I have a viewstack in my main application

public var currentStep:int;

<mx:ViewStack id="step" selectedIndex="{currentStep}">
     <comp:Choosecar id="choosecar" />
     <comp:Configcar id="configcar" />
</mx>

I'm using a drag and drop inside to choosecar component, so I want to change the 'currentstep' - which is a variable of the main application - with +1 so the viewstack changes to the second component 'configcar'. The only solution I found is calling a component from the main application, I need it the other way around but I can't find it.

Can anyone help me out please?

Thanks!

In your component Choosecar, you may dispatch an event, let's say "switchToConfig". I assumed you meant dropdown instead of "drag and drop".

<mx:ComboBox change="dispatcheEvent(new Event('switchToConfig'))" />

At the beginning of your component's MXML you have to declare the dispatched event:

[Event(name="switchToConfig", type="flash.events.Event")]

Now you will be able to catch the event in the top application

[Bindable] public var currentStep:int;

<mx:ViewStack id="step" selectedIndex="{currentStep}">
   <comp:Choosecar id="choosecar" switchToConfig="currentStep = 1" />
   <comp:Configcar id="configcar" />
</mx>

Cheers
