matamel, thanks for the reply.
The point is that there the app does not crash, so there is
not much information in the log.
First, after the execution of
public var model : ShopModelLocator =
ShopModelLocator.getInstance();
there is a log message: "didn't find all selected items"
and later after execution of
CairngormEventDispatcher.getInstance().dispatchEvent( new
CairngormEvent( GetProductsEvent.EVENT_GET_PRODUCTS ) );
there is a message issued by
Alert.show( "Products could not be retrieved!" );
So there is not much to analyze so far.
