Hi,
I need to inject an array with 3 elements object elements all of which implements the same interface.
Any idea how to do that?
Something like:

            <NestedObject id="one" 
                  type="{CustObject1}">
            </NestedObject>

            <NestedObject id="two" 
                type="{CustObject2}">
            </NestedObject>

            <NestedObject id="three" 
                type="{CustObject3}">
            </NestedObject>

        </ConstructorArgs>

10x,
Claudiu

   basically I pretty much need this scenario:

   I need a way to configure the factory with the parsers inside it.

   Hi, I don't understand the question, and I don't see how it relates to Robotlegs?

   Sorry if I am not being explicit enough.
   Basically I am using the same scenario. I have a factory and some parsing classes. the idea that each strategy class can decide is I am using if it can parse it's really neat. The thing Robotlegs to wire my application not Spring As or Parsely so I have no idea how I configure the factory class to be initialized with the parser.

     var exerciseFactory:ExerciseFactory = new ExerciseFactory();
     exerciseFactory.addParser(new MultipleChoiceDialectAParser());
     exerciseFactory.addParser(new MultipleChoiceDialectBParser());
     exerciseFactory.addParser(new FillGapsDialectAParser());

   with Spring As this code is configure like this:

   
   

   When you want to use it you just inject it into your client and that's it. The same goes for parsley only the syntax is more similar to my first post. How can I define the array than the 3 custom parsers inside it?

   Hope this makes sense.

   I left this aside for a while due to low priority but ultimately I went ahead went this:

   Context/Command

   var parsers:Array = injector.instantiate(Array);
   parsers.push(injector.instantiate(CustomParser1));
   parsers.push(injector.instantiate(CustomParser3));
   parsers.push(injector.instantiate(CustomParser3));
   injector.mapValue(Array, parsers, "parsers");

   factory class:

   [Inject(name="parsers")]
   public class FactoryClass
   {

   private var _parsers:Array;
   
   public function MessageParserFactory(parsers:Array)
   {
       _parsers = parsers;
   }

   }

   Seems to do the trick. Anyone knows a better way of doing this if any ?

   It's a shame though you cannot inject Vectors instead of Arrays. Anyone knows when that will be possible?

   In these cases it's better to wrap your object in a VO - then you can have a Vector of the items rathe than just the array.

   Always, always avoid injecting the base classes.
