In these tutorials, you used the following two methods for listening for events:

addViewListener
addContextListener

I was wondering whats the difference between those and the one used in your TwitterClient screencast:
eventMap.mapListener

Thanks

I think you shouldn't move the creation of new Tweet objects outside the loop... otherwise, you'll end up inserting the same object into all the Array cells... which means the same tweet will be repeated in the list.

Of course there is. ;)
You could create a "component" combining some buttons and elements that are used together, that dispatch certain events or offer a certain API for a Mediator.

Or you could handle it with a different structure: have a look at "Presentation Patterns" as e.g. described here: http://blogs.adobe.com/paulw/a...

But you should be aware that, what I know of, robotloegs only brings MVCS as a "reference implementation" with it, which doesn't support e.g. "Presentation Model" as easy.

Hoping that answers your question,

Thank you so much for this useful screencast.

I see that you create a view/mediator for everything... things as small as buttons... when working on a large scale project, a single view could have tens of these small view/mediators. Is there a different way of handling these things?

Thanks

Nice book! Do you have a tutorial about separating view-logic from the mediator. I saw it in the book and want to try it out, but I really don't know were to start :X.

Re: An Introduction to Robotlegs AS3 Part 1: Context and Mediators

Anna — Fri, 02 Mar 2012 08:16:51 -0000

I don't know if I understand correctly, but this is what I want: if I want to inject the MessageView in my mediator like this: [Injector]private var myMessageView:MessageView; .

I see it is possible like that, but are their some drawbacks??

Re: An Introduction to Robotlegs AS3 Part 1: Context and Mediators

Joel Hooks — Thu, 01 Mar 2012 10:40:48 -0000

Injections occur externally. The Injector has no access to private member variables. I know some folks that have done interesting byte code manipulations to make it possible, but with RL, that isn't the case.

You always inject a view as a public var, why not private? Is there a difference?

this is an old post but just in case ppl are still reading - did you find a solution for this? I have the same problem trying to build a pure as3, robotlegs-signals example. cheers

Re: Robotlegs, AS3-Signals and the SignalCommandMap Example

mike — Wed, 22 Feb 2012 23:42:24 -0000

Is this a flex only sample? I've tried to work this into a pure as3 example but extending SignalContext says super() accepts 0 parameters. If thats the case how do u pass in a context view? Great article btw :)

I don't think so. I can't investigate until this weekend. You can ask on the http://knowledge.robotlegs.org and might get a faster collaborator.

Hi Joel,

I just tried and it does not work for me.
Here is wjat I am doing:
1. In the AppConfig I have added following lines:
mediatorMap.map(TestPopupButton).toMediator(TestPopupButtonMediator); //button on popup window mediatorMap.map(TestPopupWindow).toMediator(TestPopupWindowMediator); // and popup window itself
2. And here I open popup:
var w:TestPopupWindow = new TestPopupWindow(); PopUpManager.addPopUp(w, FlexGlobals.topLevelApplication as DisplayObject);

Am I missing something?

That's a good question. Give it a try ;)

Hi Joel,

Is flex popup mediating properly with RL2?

Re: Modular Robotlegs

jmp909 — Thu, 19 Jan 2012 13:15:14 -0000

for anyone interested, the slow down with multiple doodads appears to come mainly from the console logging not the modular nature. if you remove the console from the app the modules are a lot more responsive even when adding a few.

Great example thanks Joel. this and http://labs.riamore.com/conten... got me up to scratch with RobotLegs & Flex, for some of these more complicated applications of the frameworks, from a beginner in in a few days

Ok i updated my SignalsCommandMap swc to the v0.4 version and along with my constructor fix in FoodItemSelected everything works without warnings now

SWCs used:
as3-signals-v0.8.swc, robotlegs-framework-v1.5.2.swc,
signals-extension-SignalsCommandMap-v0.4.swc,
SwiftSuspenders-v1.5.1.swcHope this is useful to people

jmp909 — Fri, 13 Jan 2012 18:39:06 -0000

sorry about that.. line breaks not showing.. those other parts are my trace outputs to follow the function signal flow.. the warning is:

Warning: Injector already has a rule for type "org.robotlegs.examples.signalcommands.model.enums::FoodType", named "". If you have overwritten this mapping intentionally you can use "injector.unmap()" prior to your replacement mapping in order to avoid seeing this message.

Re: Robotlegs, AS3-Signals and the SignalCommandMap Example

jmp909 — Fri, 13 Jan 2012 18:37:48 -0000

i've managed to get this sort of working with:
as3-signals-v0.8.swcrobotlegs-framework-v1.5.2.swcsignals-extension-SignalsCommandMap.swcSwiftSuspenders-v1.5.1.swchowever note the following..

I had to add a constructor function to the FoodItemSelected signal

public class FoodItemSelected extends Signal { public function FoodItemSelected() { super(FoodItem); } }

this removes the following error that was occurring with other versions:

[Fault] exception, information=Error: Injector is missing a rule to handle injection into property "item" of object "[object FoodItemSelectedCommand]". Target dependency: "org.robotlegs.examples.signalcommands.model.vo::FoodItem", named ""

but there's a warning on the Injector...

AddFoodItemToOrder::FoodSelectionView::addFoodItem_clickHandlerFoodSelectionViewMediator::handleItemTypeAddedAddFoodItemToOrderCommand::executeFoodOrderModel::addItemToOrderCurrentOrderViewMediator::updateOnItemAddedFoodItemSelectedCommand::executeCurrentOrderViewMediator::updateOnOrderUpdatedFoodSelectionView::addFoodItem_clickHandlerFoodSelectionViewMediator::handleItemTypeAddedWarning: Injector already has a rule for type "org.robotlegs.examples.signalcommands.model.enums::FoodType", named "". If you have overwritten this mapping intentionally you can use "injector.unmap()" prior to your replacement mapping in order to avoid seeing this message.

I'm not sure what's happening there then. The application works now, but there's obviously still an issue

> "this just doesn't make any sense to dig through the context to get at the dependency that I really want."

I agree. The IContextConfigs currently in Robotlegs 2 have a lot of code like:

context.injector.getInstance(IMediatorMap)

Using the context to get the injector to pull out a dependency from the injector--this gets my Demeter-sense tingling. I feel it would be more straightforward to just inject the IMediatorMap into something and skip the pretext of "configuring the context".

Re: Robotlegs 2 (beta): Flickr Image Gallery

Robert Penner — Wed, 04 Jan 2012 22:21:58 -0000

I agree with you on the last point. Obviously making custom Events is not my favourite thing, either.

Re: Robotlegs 2 (beta): Flickr Image Gallery

Robert Penner — Wed, 04 Jan 2012 22:19:28 -0000

Or you could *gasp* execute the command manually. =) Your point is taken, though. Maybe we should make it easier to execute commands then. Or make it easier to inject into functions in general.

Remember that the context is not fully initialized at those points, and all dependencies have not necessarily been mapped, so automated injection into those configs is not feasible.
