Dependency Injection (YADIF), Netbeans and Autocomplete - netbeans

I've set up a YADIF (Yet Another Dependency Injection Framework) to handle most application dependencies in a Zend framework app - one problem,it kills auto-complete.
Has anyone else had this problem? My general solution is to use YADIF for re-usable library classes, but use "new" for application work (i.e. in controllers or items that extend ZF, since I don't want to go to the trouble of stubbing out Zend in my Unit Tests)

I just found the answer(s) to this inadvertently, so I've added it on behalf of anyone else who encounters this issue:
This solves auto-complete issues for method scope - but doesn't seem to work for class level variables (i.e. variables preceded by $this):

to set up autocomplete for class instance variables, use #property:

IoC, MVC4 Web API & HttpParameterBinding/ParameterBindingAttribute

I'm using ASP.Net MVC 4 RTM Web API. I have a controller action with a parameter that I'd like to populate via custom model binding. To achieve this, I created a class that derives from System.Web.Http.Controllers.HttpParameterBinding that sets the value of this parameter. I then created an attribute class that derives from System.Web.Http.ParameterBindingAttribute which I use to decorate the parameter on my controller action.
This is all working great, my HttpParameterBinding class is populating the action parameter correctly. The problem I have is that my custom parameter binding class has a dependency that I'd like resolved via my IoC container (Unity). Is there a way to override how Web API creates HttpParameterBinding instances so that I can build up my custom binding class dependency from Unity? I was able to do something similar for a filter attribute by creating a custom filter provider that uses Unity's BuildUp method to populate dependencies, however I'm not seeing anything similar for Web API's HttpParameterBindings.
In general: to use IoC / Unity in the Web API you need to set it up seperately.
Try downloading the nuget package Unity.WebApi and see if that helps!
Take a look at this article: Parameter Binding in WebAPI
It walks through a couple different options from Converters to Binders to BinderProviders. It sounds like you may be able to write a custom ModelBinderProvider which knows how to provide your dependency. If that isn't high enough in the chain you can look at replacing the default IActionValueBinder service. It's a DefaultActionValueBinder instance, which you can extend or simply re-implement.
I also highly recommend downloading the WebAPI source code, as it's been an incredible help for these issues as I've run into them. Here's the WebAPI source code. I recommend downloading it so you can open it in VS for easy navigation.
Feel free to check out FlitBit too (It's very modular, don't let the number of packages scare you off)! I'm working on a WebAPI package for supporting FlitBit, specifically FlitBit.IoC and FlitBit.Dto. I'll add an update if I work out my IoC issue, since it's very similar to yours.

Programmatically configure ActiveRecordFacility for multiple databases

I'm trying to build a small application (ASP.NET MVC) that uses the plugin architecture. Along with Castle ActiveRecord Integration Facility. And I wish to let each plugin configure its own ActiveRecord behaviors. Like database connection string, proxy, etc..
However, I couldn't find a way to set multiple configurations without the use of web.config. The idea is to make this programmatically.
My goal is for each plugin in this system, if it defines its own ActiveRecord settings, the main application can set up next to ActiveRecordFacility these behaviors.
has someone do something like that?
P.S.: sorry, bad grammar...google translate...;P
You can set up the ActiveRecord configuration programmatically using InPlaceConfigurationSource (lots of examples around), then after initializing ActiveRecord (in your own code), call the ActiveRecordFacility with the skipARInitialization flag. e.g.:
container.AddFacility("ar", new ActiveRecordFacility(true));
This tells the facility not to try to initialize ActiveRecord, so it picks up the existing configuration.
Ok...the example in Lostechies works great. (link text)
Mauricio, thanks for the tip!

How do I get my Objects to work in ASP.NET MVC2

I'm rather new to MVC2 (never been in MCV1) though I'm a WebForms developer for some years now...
in my MCV 2 start project I created a App_Code folder that I would put my Business Classes on it, I also add 2 References to 2 DLLs used for the API I'm about to use.
But I don't get Intellisense on the referenced objects
What am I doing wrong?

Is this so much different from the WebForms part?
Added
Even if I put the Object in Models instead App_Code (where I normally put all code in WebForms) I still don't get the normal intelisense, so... it just tells me that something is wrong ... dang! MVC is hard! I probably should do this in WebForms...
alt text http://www.balexandre.com/temp/2010-07-28_1509.png
This has nothing to do with MVC2, and everything to do with you're doing it wrong. I can tell that its a possibility, as you're using App_Code (I mean, who does that?). I'd definitely suggest backing up and reading some MVC tutorials, as it IS much different (although not in the way you're asking about).
I'm not exactly sure WHAT you're doing wrong, however. It might bethat PerceptiveMCAPI is internal to the assembly, it might be because there is a bug in VS, it might be that you haven't imported the correct namespace... it could be a number of different things.
I'd do the following: 1) load the assembly in reflector and make sure you have the namespace and type name and that it is public 2) use the fully qualified name of the type 3) compile, check all errors and 4) restart VS.
If all else fails, Connect.
See the Models directory -- that's where your model classes would go, assuming the class is a view model class. Having said that, it should be able to pick up and provide intellisense for whatever references you add. App_Code isn't really intended for a Web Application project (the type used by MVC) where the code is compiled statically, but rather for a WebSite where the code is compiled dynamically at runtime. It could be the "special" nature of the directory that is causing the problem because it doesn't fit the project type. You might try simply creating a different directory (if Models isn't appropriate) and not use the special App_Code directory for your code. A separate class library project with a project reference in the web application would be another alternative and is the one I usually use for non-viewmodel/controller code.

Is there a tool to convert my GWT RemoteServiceServlet into the correct Service and ServiceAsync interfaces?

I'm working on a GWT project and I find it very tedious to have to add a function to my servlet, then copy and paste the function signature into my Service interface, then copy and paste it into my ServiceAsync interface and change the return parameter to be a callback. Is there a tool or a setting where I can just add public methods to my class and they can get copied into the other interfaces? Even if its not automatic it would be nice to be able to select specific methods and have them copied automatically.
I'm using eclipse and ideally it would update my interface each time I save implementation since thats when it checks my code and complains that my changes break the interface.
If you add the method to your *Service interface, then Eclipse can auto-generate the method ("Add unimplemented methods...") in your *ServiceImpl servlet, which you can then just fill in. Also, if you've got the Google Eclipse plugin installed, it will underline the new method in your *Service interface and complain that it's not in the *ServiceAsync. It might have a CTRL + 1 option to generate it in that interface as well.
You don't really need a tool. Just factor out the many RPC methods by just one method that takes a Request/Response. all you need to do is create subclasses of Request/Response and you don't need to think about adding new methods in the 2 interfaces.
You can use Google Guice on the server side to map the incomming request to a class handling the call... or you could use a visitor approach to forward the incoming request to the code handling the request (without resorting on a big instanceof construct).

GWT Composite best practices

I'm learning GWT and have started to get the hang of it. I'm at the point where my code is getting to be a spaghetti mess so I'm going back and factoring reasonable bits of it out as Composites. The first problem I ran into was that my tool support failed to give the new Composite class an initWidget() method. It did include a default constructor.
For the time being, I've simply filled in my overridden initWidget() method with a call to super(initWidget(w)) My project compiles and runs as expected, though I feel as though I must be missing something.
What should I keep in mind when overriding init and what if anything do i need to place in the constructor. Is there anything else that I need to know or does it just boil down to regular old Java after this?
Clarification - It has occurred to me that there are probably different answers to this question depending on whether you intend to release said Composite classes as part of a library or simply part of your stand-alone app. I in particular have no intention at this time of developing externally useful components (mainly because I'm so green in this particular technology.)
Thanks!
I'm not sure if I understand what you are trying to do. But for all the Composite's I've written I've never overridden the initWidget method. Because Composite itself doesn't need to be initialized with a constructor, i.e. no need to call super() my constructors of widgets extending composite look something like:
public mywidget() {
SomePanel p = new SomePanel();
....
initWidget(p);
}
As a best practice, imo, only the widget extending Composite should call it's 'own' initWidget.
"GWT Conference: Best Practices for Building Libraries" gives a couple of tips. You should also look at the source of GWT and at the source of one of the libraries for GWT (like gwt-ext)
[EDIT] I just saw another option: suco. From the description:
