[flexcoders] Incremental compiling -- should I have long build times?
Hi, I'm wondering if incremental compiling is working. Building takes the same amount of time whether I make one minor change to one file, or a clean build -- about 25 seconds. Is there any way to verify that the project is being compiled incrementally? thanks -- Flexcoders Mailing List FAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt Search Archives: http://www.mail-archive.com/flexcoders%40yahoogroups.com Yahoo!

[flexcoders] Re: Some Cairngorm questions
Our VO classes are separate from the model. We found that the model needed stuff that didn't belong in the VOs, for example, fields that don't get persisted to the db, state variables, and various methods that the classes in the model need. When we do need a VO to pass to the data layer, we call toVO(), which, you guessed it, gives us a plain ol' VO. We didn't get too far into our project before we realized that model != VOs. The code that knows what parts of the model need to be persisted, and when and how to do it is in a separate utility class that we call a persistence manager. It has all the logic that was cluttering up the Commands. Now the command just uses the persistence manager in a very simple way, like pm.saveCar(car). So each command is back to fitting one screen, which I think is nice.

[flexcoders] Re: Some Cairngorm questions
We are pretty much sticking to textbook Cairngorm. We all just began to question the FrontController. Most of my MVC experience is with struts, where it seems to make more sense. As for reusing events and commands from different places, most of what I could find from the Cairngorm creators suggest that Commands be specific use cases and a Command should always know its context. I suppose if the event payload indicates the context, then you're not violating this rule. I hadn't thought about doing this. By "something else" I was referring to something other than a Command (say, a model object) consuming the Delegates. Anything wrong with this?

[flexcoders] Re: Some Cairngorm questions
Ben, Thanks for your viewpoint. I'd like to summarize your points to see if I understood correctly: 1) It's easy to execute a Command by raising a Cairngorm event. It seems to me that the amount of code to raise a Cairngorm event is the same as executing the Command directly. Probably the same # of imports. 2 lines of code to raise a cairngorm event. 2 lines of code to instiate and execute a Command. 2) FrontController keeps instances of the Command in one place. I'm not sure this is technically true. To me, the more imporant thing to control is the various places that you're raising Cairngorm events, which can get messy in a large app. We typicallly try to raise Cairngorm events at the highest level possible in a module. Again, the fact that raising the event is not the absolute direct execution of a Command is almost meaningless. 3) Changing the name of a Command is easy because you only need to edit a line or 2 of code in the FrontController. True. But you're still raising Cairngorm events by name/type. If you rename the Command, you'll most likely want to rename the Cairngorm event type. Now you're back to having to find all the places where you're raising that particular event type. This actually shouldn't be much of an issue due to the fact that Commands are supposed to be context sensitive, i.e. the Command should know what screen/module/component caused it to be executed. Therefore, there are usually a small # of places where any one event type gets raised. This context sensitivity is another way in which application code really isn't abstracted from Commands in a meaningful way. I screwed up on my initial explanation of what we're doing with our model. We're still using Delegates.. no direct calling of remote objects. What we are doing is moving the code that uses delegates from Commands to the Model. Again, the reasoning here is that when you do something like (contrived example here...) car.save(), car being a model object, only the car knows what save() really involves, based on state in car and its various components and logic within the car, etc. So the car needs to use Delegates, implement IResponder (or Responder), etc. I think a big benefit we've received from Cairngorm on our current project is the consolidation of the use cases or "features" into one place, or one tree on the file systems. This seems to facilitate team development some since there is a single place to go and see what use cases exist. The struggle for us has been keeping the Commands very light, thus our initiative to move the logic and delegate calls from some of the really big Commands into the model.

[flexcoders] Some Cairngorm questions
Hi, I've got a couple of questions on my mind that I'm hoping to get some opinions on... First. I don't see what value the FrontController adds in Flex apps. My initial thought was that it was important to prevent views from coupling to specific commands. That really doesn't hold up though, because the views are coupled to specifc events, each of which results in a specific Command being executed. Since the FrontController maintains a 1-to-1 map of Cairngorm events to Commands, why don't views just run the commands directly? Next, we're moving most of our remote object calls into the model. The logic that controls what parts of the model get persisted, when, and in what order is complex, and our Commands had become huge and full of logic. As a reuslt of the changes, lots of the classes in the model now make remote calls and implement IResponder. I'm trying to get back to the model of Command kicks off the "feature" and then gets out of the way. Is there any rule with Cairngorm that says that Commands must do the remote calls? Is it common to use something other than a Command to make remote calls? thanks Jeremy -- Flexcoders Mailing List FAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt Search Archives: http://www.mail-archive.com/flexcoders%40yahoogroups.com Yahoo!

[flexcoders] defaultButton and viewstack issue
Hi, One of the children of the ViewStack has the defaultButton defined. The problem is that if a different child of the ViewStack is visible, pressing enter on one of its text boxes fires the click of the defaultButton for the hidden ViewStack child. The docs say "When controls in the container have focus, pressing the Enter key is the same as clicking this Button control." The button that gets "clicked" is on a container that does NOT have focus. The only workaround we've found is to define defaultButtons for all the viewstack's children. Is there a better solution to this? thanks Jeremy -- Flexcoders Mailing List FAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt Search Archives: http://www.mail-archive.com/flexcoders%40yahoogroups.com Yahoo!

[flexcoders] tokens in services-config.xml. magic?
Hi,
So services-config.xml has some nice tokens like {server.name},
{context.root}, etc. I can't seem to find a list of these pre-defined
tokens in the documentation. Anybody know where this would be? It
appears that some of these are resolved to their values at runtime by
the SWF. So, this don't seem to be the same type of tokens that get
resolved at compile-time. Can someone shed some light here?
A point of clarification.. there are some references to these tokens
in the documentation in the form of example snippets. What I'm
seeking is a list of tokens that you can use, and when/how they get
resolved to values.
thanks

[flexcoders] Cases when a view should update ModelLocator?
For example, when a button is pushed, a property on the ModelLocator needs to be updated, which as a result changes which screen is visible. I'm trying to be pragmatic with MVC here. Is it advised to implement a Command for such a simple "feature"? thanks Jeremy Yahoo! Groups Sponsor ~--> Check out the new improvements in Yahoo!

[flexcoders] Re: binding ViewStack.selectedChild to the data model
thanks. I successfully switched to using selectedIndex. Curious
though, would the solution you provided create a binding? Seems like
it might be a one-time assignment to selectedChild and not receive
updates.

thanks for the response. I think it solves the problem, however the
pseudo-private constructor can only be enforced at runtime.

[flexcoders] ModelLocator - Cairngorm 2
I can't get the reference implementation to compile (pasted below).
Seems to be missing a constructor. How should this be solved keeping
in mind that private constructors aren't supported?
[Bindable]
public class ShopModelLocator implements ModelLocator
{
private static var modelLocator : ShopModelLocator;
public static function getInstance() : ShopModelLocator
{
if ( modelLocator == null )
modelLocator = new ShopModelLocator();
return modelLocator;
}
public var products : ICollectionView;
}

[flexcoders] bidirectional binding
I find myself wanting to do bidirectional binding, but I have the feeling there may be some drawbacks to this. I want a screen's controls to be initialized (bound to) a data model. As the user changes the controls' values, I want the data model to reflect this. In this case the data model is basically a VO. Is there a best practice for this? thanks Jeremy Yahoo!

[flexcoders] intermittent code hints
The scenario is an .mxml file that is the sole includer of an .as file. Using the FB2 plug-in, sometimes, we get code hinting in the .as file, other times not. When we do get code hinting, all the variables from the enclosing .mxml are available. One of our developers is not getting any code hinting in the .as file. Any idea what could cause this? Also, how would FB handle code hinting of an .as file was included by multiple .mxml files? Does it give you code hinting for the variables in all the .mxml files, or none? thanks Jeremy Yahoo!

[flexcoders] Re: RemoteObject calls failing
thanks for the reply.
from the channel def:
uri="http://{server.name}:{server.port}/{context.root}/messagebroker/amf"
class="flex.messaging.endpoints.AMFEndpoint"/>
I also tried replacing {context.root} with "flex". I actually tried
hard coding values for all 3 of the merge fields, which didn't seem to
have any effect. I've got tomcat on my machine and I'm running from
eclipse, so the browser is using http.
Is there anything else I should check?

[flexcoders] Re: RemoteObject calls failing
I tried replacing {context.root} with "flex" once more and it worked.
I think I didn't recompile properly the first time I made this
change. Still curious, where would I pass a --context.root parameter?
thanks so much for the help.
