Hi,
I'm trying to extend a transactional class to create a nifty
properties-class that auto-saves, keeps key-values updated and is
transactional. My final aim being to create a bunch of test-cases for
transaction failure handling and retry-policies.
I got code like this:
private static readonly ProxyGenerator _Generator = new ProxyGenerator();
public static IWindsorContainer CreateContainer<TSettings>() where TSettings
: SettingsBase
{
var c = new WindsorContainer();
c.AddFacility<FactorySupportFacility>();
c.AddFacility<TransactionFacility>();
var options = new ProxyGenerationOptions(new
SettingsProxyGenerationHook());
c.Register(
Component.For<ITransactionManager>().ImplementedBy<DefaultTransactionManager
>(),
Component.For<TSettings>()
.UsingFactoryMethod(k =>
_Generator.CreateClassProxy(
typeof(TSettings), options, new
object[] { c.Resolve<IFileAdapter>() },
new AutoSave(),
new GetProperties()) as TSettings)
.LifeStyle.Transient
);
return c;
}
public static TSettings CreateSettings<TSettings>() where TSettings :
SettingsBase
{
var s = CreateContainer<TSettings>().Resolve<TSettings>();
return s;
}
[Test]
public void CreatingSettings()
{
CreateSettings<PropertiesSettings>();
}
Which yields this exception:
Test 'ProxyTests.CreatingSettings' failed:
Castle.MicroKernel.ComponentActivator.ComponentActivatorException :
FactoryActivator: could not proxy Castle.Proxies.PropertiesSettingsProxy
----> System.ArgumentException : Can not instantiate proxy of class:

ProxyTests.CreateSettings[TSettings]()
SettingsBaseTests.cs(59,0): at ProxyTests.CreatingSettings()
What is the best way to go about fixing this? Is there a way to specify a
generation hook through the fluent registration api, so that I don't have to
use a factory method? What am I missing?
SettingsBase, that abstract base class for PropertiesSettings (I had a
bright moment naming that one!), has the TransactionalAttribute attached.
Cheers
