I'm developing a complex application using modular-architechture and RSLs (Runtime Shared Libraries). And I'm using a Mate as a main framework.

Instead, when creating the module via a "factory" I insert a copy of the data object manually. Upon initialization, the popup module re-types the 'generic' data object into what ever VO it was expecting. The 'true' module class does not get inserted into the main application and the data is simply a copy of the appropriate main application's value-object. Seems to work fine.

The forecast is not the object the service returns, but it is within a property of that object (Details). Therefore, to make it work as is, you just need to do this in your WeatherManage.storeWeather() function: currentWeather = latest.Details; To see what the service returns, you just need to put a breakpoint in the storeWeather function. Regarding your questions: 1) Using PropertyInject may or may not be the best way, it depends on the particular use case. It seems fine to me in this case. What it doesn't look fine to me is that you are extending the datagrid. I see no need to do that. Just placing the Datagrid in your view is fine, though I would move all UI code to its own starting parent view, instead of the main application. 2) Instead of dispatching an event from the view, you can use a different pattern (Presentation Model) and dispatch the event from there. 3) Specifying debug=true in the Injectors will simply let you know that the binding (or one-time copy) has taken place. If you want to see that the bound properties get updated when the source value changes, you could create setters instead of public properties and put breakpoints/trace statements there. A note: <blockquote> "StockQuoteExample gets a simple response from its web service, so there is no problem storing the result in a Label field" </blockquote> This is not exactly true. The webservice doesn't return a simple string, it actually returns an XML object with a lot of properties. But the manager only stores the last price. (See the StockQuotes webservice version) The result is not stored in a label field, the value is stored in the manager. This value can be anything, a VO, an array, anything. The PropertyInjector makes sure the view gets this value, whatever the type might be. The view uses that value the way it makes more sense to the view. If the value is a string, it may use a Label to show it. If the value is an array, it may show it in a datagrid. mslinn on "Problem generalizing StockQuoteExample" http://mate.asfusion.com/forums/topic.php?id=168#post-745 Sat, 04 Oct 2008 02:04:24 +0000 mslinn 745@http://mate.asfusion.com/forums/ I've put together a Flex Builder project patterned after StockQuoteExample. This example (weather5) retrieves the next 7 day's weather forecast from a web service. StockQuoteExample gets a simple response from its web service, so there is no problem storing the result in a Label field. I encountered a problem when attempting to pull apart the weather forecast data coming back from the web service call in order to store it in a DataGrid. The DataGrid was made into a component called WeatherGrid in order to follow the pattern of the StockQuoteExample. Instead of pasting all five files here, the project can be downloaded for a limited time from <a href="http://introducingmate.com/weather5.zip" rel="nofollow">http://introducingmate.com/weather5.zip</a> Questions: 1) Is a PropertyInjector the best way to populate the DataGrid with the result? If not, please show an alternative. This mechanism does not work! 2) This project's code organization is nice in that the WeatherGrid has no business logic in it. The main view (weather5.mxml) only has the getWeather() definition. How might one remove even that bit of code from the view, and still cause the weather to be looked up when the button is pushed? 3) What debugging strategy would you recommend? Attempting to debug the PropertyInjector was not fruitful. gsb on "Modules and Local EventMaps" http://mate.asfusion.com/forums/topic.php?id=162#post-744 Fri, 03 Oct 2008 20:06:51 +0000 gsb 744@http://mate.asfusion.com/forums/ " ...I use "injectors" to supply the module with data upon opening and "events" sent back to the main application (EventMap) for user input resolution; like a close event.

It is one of the limitations of using SmartObject. The reason behind that is that Bindings in the EventMap will run only once at the beginning. The value of fault, event, resultObject, etc is not calculated until the EventHandlers fire. If you try to do a concatenation, what happens under the hood is that FlexBuilder tries to concatenate a SmartObject with a String and not the actual value of the SmartObject (which is calculated when the handlers fire). iconara on "New repository for example applications" http://mate.asfusion.com/forums/topic.php?id=155#post-741 Fri, 03 Oct 2008 19:12:43 +0000 iconara 741@http://mate.asfusion.com/forums/ For those who are interested in how to test user interfaces I have now checked in some test cases for the application.

As mloncaric said, you need to pass the smart object (or one of its properties) as a whole object. You can do: <code> arguments="{[Navigation.ERROR, fault.faultString]}"/> </code> I thought I had something about that in this page: <a href="http://mate.asfusion.com/page/documentation/tags/eventmap/using-smart-objects">Using Smart Objects</a> at the bottom . The concatenating part was missing, so I just added it. mloncaric on "Weird string concatenations" http://mate.asfusion.com/forums/topic.php?id=167#post-738 Fri, 03 Oct 2008 16:06:53 +0000 mloncaric 738@http://mate.asfusion.com/forums/ I often get that kind of result when I use lastReturn or some other custom variables.. I've solved that kind of problem many times before by sending the whole event to the function not just event.property. Have you tried <code>.. arguments="{[Navigation.ERROR, fault]}"/></code> instead of <code>.. arguments="{[Navigation.ERROR, 'Error while saving: ' + fault.faultString]}"/></code> If I was you I'd put that 'Error while saving: ' string into NavigationManager::navigate method. EDIT: .. or better, just send one custom value object, which contains event type, message, data to that navigate function if you want to create an "flexible" function. iconara on "Weird string concatenations" http://mate.asfusion.com/forums/topic.php?id=167#post-737 Fri, 03 Oct 2008 11:26:45 +0000 iconara 737@http://mate.asfusion.com/forums/ I've got a really strange thing happening in my event maps. When I try to concatenate a string with a variable value to use as the argument to a method the string seems to be concatenated at compile time. When this code (which is triggered by a HTTPService fault) runs: <pre><code><faultHandlers> <MethodInvoker generator="{NavigationManager}" method="navigate" arguments="{[Navigation.ERROR, 'Error while saving: ' + fault.faultString]}"/> </faultHandlers></code></pre> The second argument to <code>navigate</code> is "Error while saving: fault.faultString", literally. Somehow the "fault.faultString" part becomes part of the string, even though it should be evaulated at runtime to the fault message (the expected string would be something like "Error while saving: could not connect"). If I add <code>-keep</code> to my compiler flags I can find how the line above is translated into ActionScript, and it looks like this (showing only the <code>arguments</code> part): <pre><code>[Navigation.ERROR, 'Error while saving: ' + fault.faultString]</code></pre> Which is what I wrote in MXML verbatim. Clearly then, the error is not in the translation from MXML to AS. However, if I run the application and place a breakpoint in the <code>navigate</code> method the arguments have been concatenated into "Error while saving: fault.faultString", and this is true as far back as I can see in the stack trace. It doesn't seem to be Mate that's doing anything wrong, but a compiler bug. Has anyone else seen this, and do you have any suggestions for a workaround? I've tried putting the parts in an array an join them, like this: <pre><code>arguments="{[Navigation.ERROR, ['Error while saving: ', fault.faultString].join('')]}"</code></pre> But that just comes out as "fault.faultString" (the first part being left out altogether). iconara on "LocalEventMap and components" http://mate.asfusion.com/forums/topic.php?id=166#post-736 Fri, 03 Oct 2008 08:33:28 +0000 iconara 736@http://mate.asfusion.com/forums/ Does Mate provide a component defined in Module any extra functionality over a component subclassed from another Flex component?

All user gestures* should result in method calls on the presentation model object. In most of the presentation patterns, the presenter object acts as a Mediator** between the view and the application controller and application model, and translates requests coming from the view into requests that the application controller can understand. When I use the Presentation Model pattern in Mate I let the view call methods on the presentation model object and let it translate these into events that are dispatched to the event map (the application controller). The view is has no knowledge of how the application works, and even though it could, in theory, dispatch events that would bubble up to the event map, it shouldn't since that is the job of the presentation model object. Doing it would break the separation. Does this answer your question, or you have something more specific in mind? * "User gesture" means any action that the user takes, it's not always a clearly defined term but here I use it to mean things like "close window", "remove item", "new document", etc. ** PureMVC also uses the term "mediator" for its presenter, but I'm not referring that particular pattern (which happens to be Supervising Presenter). Mediator is a design pattern that introduces an object that knows about two other and "mediates" between them so that neither has to know anything about the other.

Dispatching events tend to be more error-prone, and is harder to understand at a glance. - and of course the benefit of having state logic separated from the view code, but you get this with Supervising Presenter and Passive View too.

Does anyone know of a way around this? I.e. how to specify an injector in the main application into a module class without having a reference to the Class of the module? Seems too fundamental to Mate to avoid. (Not that you can't do it other ways, with events, or specifying the injection in your module event maps.)

That's what I was looking for! <MyLocalEventMap dispatcher="{this}" /> Now I get it. Was thinking the dispatcher was specified in the event map. It makes a lot of sense to specify to the map what we're considering local. Very flexible.

Mate lets you do what you like. I wouldn't say it "best" enables anything. It just provides the glue to shovel your data (including events) around where you want it. Between <code>Listeners, Dispatchers, Injectors</code> and <code>EventHandler</code>s there's no MVC-style/related patterns you can't implement... gsb on "Modules and Local EventMaps" http://mate.asfusion.com/forums/topic.php?id=162#post-719 Thu, 02 Oct 2008 02:39:22 +0000 gsb 719@http://mate.asfusion.com/forums/ I use modules... well only one at the moment. I use them as "Views" mostly and as such they are independent; they do not know of each other. I use "injectors" to supply the module with data upon opening and "events" sent back to the main application (EventMap) for user input resolution; like a close event. In your case I would think in terms of "Event Aggregation." That is, using the main application's "global" EventMap as a clearing house; receiving, resolving and as needed, forwarding events/data throughout the module structure. ...or so I think just now. greg charlie on "Modules and Local EventMaps" http://mate.asfusion.com/forums/topic.php?id=162#post-718 Thu, 02 Oct 2008 02:33:38 +0000 charlie 718@http://mate.asfusion.com/forums/ We struggled for half a day yesterday trying to get a LocalEventMap to work. Like Nahuel said you need to set the dispatcher, which you would normally set like this: <code><MyLocalEventMap dispatcher="{this}" /></code> We are using EventMaps in modules. If you want a particular EventMap in a particular module to handle an event you have two options: create an event type that is specific to that module, or use a LocalEventMap so you only see the events in that module. The LocalEventMap way is more flexible and combined with the local cache is simple and correctly separated from your main app. You can then grab values out of your global cache. E.g. this is our SliceController class, which is a LocalEventMap inside a module: <pre><code><LocalEventMap xmlns="http://mate.asfusion.com/"> <Injectors target="{SliceBuilder}" debug="true"> <PropertyInjector targetKey="user" source="{UserManager}" sourceKey="currentUser" sourceCache="global"/> </Injectors></code></pre> This grabs the <code>user</code> property off the UserManager instance that's stored in the global (application wide) cache and dumps it into the <code>SliceBuilder.user</code> property whenever a SliceBuilder gets instantiated in our module (actually in this case the SliceBuilder is the main module class). BTW thanks Nahuel for the LocalEventMap stuff, it's great!

When I echo from one, it echoes to both modules. The only reason I can see for this is that my EchoManager is shared between them. I create it with an ObjectBuilder and specify cache="local"...so shouldn't that make it so that both maps create their own? I'm still using <EventMap> rather than <LocalEventMap>. When I debug, I see: Cannot debug <MethodInvoker arguments="dsvdw" method="setData" cache="inherit" generator="[class EchoManager]" registerTarget="true"/> Cannot debug Cannot debug <MethodInvoker arguments="dsvdw" method="setData" cache="inherit" generator="[class EchoManager]" registerTarget="true"/> Cannot debug Well, that's not very helpful. :-) Are there any examples of module-based Mate? gsb on "About Mate and Presentation Patterns..." http://mate.asfusion.com/forums/topic.php?id=164#post-716 Thu, 02 Oct 2008 01:00:03 +0000 gsb 716@http://mate.asfusion.com/forums/ Sorry... double posted. greg
