I am trying to call a function inside a module, from the application.

How is this done?

--- The function in the main application ---

public function cartUpdater():void {
	cartU();
}

--- The function in the module ---

public function cartU():void {
	serviceCartList.send();
}

I would suggest you define an Interface (see attachment) and implement that in your main module file (simply add "implements" attribute). In your main application you can now call (assuming the instance of the module is called "modObj"):


public function cartUpdater():void {
      MyCoolInterface (modObj).cartU();
}

package {
public interface MyCoolInterface {
    function cartU():void;
}
}

I have made the interface and imported it into the main application and the module, where i want to call the function. However i get the following error, when i call the function. I also don't know how and where to incert the "implements" attribute.

TypeError: Error #1034: Type Coercion failed: cannot convert shop_cart_small$ to shop_cart_small_update_interface.
      at shop_item_view/cartUpdater()
      at mnvitmr::shop_item_tic/inCart_clickHandler()
      at mnvitmr::shop_item_tic/__inCart_click()

I created a small flex project demonstrating everything.

Unfortunately it took me twice as long to somehow provide the file as EpxertsExchange super intelligent file-scanner doesn't allow uploading fxp Files. It allways complains about content not being allowed. I therefore uploaded the File to my confluence and you can get it from there ... http://dev.c-ware.de/confluence/display/PUBLIC/Experts+Exchange+Files)

Hope it helps.

Great example, and easy to follow.
I can se you use the mx:ModuleLoader. I have been inserting my modules, as you can se in the attached code. Is it possible to get the interface to work with this?

<ns1:shop_cart_small x="800" y="32">
</ns1:shop_cart_small>

Oh! ... you aren't using modules, you simply created a custom component ... well that's a lot easier ;-)

Just as an info: When talking about "Modules", it ususally means that you have a flex application that dynamically loads another swf and uses that inside itself.

The difference is relatively small. if your compoenent is a mxml file, then you have to add the "implements" attribute to the root tag of your component and implement the function. Now if you have an explicit instance of your component:




then you can use this to call the function:

myCart.cartU()

If you want to iterate over a list of carts, you will have to use the Cast as I used it in my code.
