Ninject Mono - Object Reference Not Set
Closed this issue · 2 comments

Seems the ActivationBlock in NinjectContainer (although not null) gives a Object Reference Not Set.
HandlerBuilderFactory
I'm still not 100% sure if this is an issue in NinjectContainerScope or Ninject itself but am happy the 'hidden complexity' is HandlerFactoryBuilder is OK (nb: v3 is supposed to be Mono 2/4 compatible) :-
handlerBlock = ".Block(Simple.Web.Ninject.Tests.TestHandler $var1) {\r\n $var1 = .Call $var2.Get();\r\n .If (\r\n .Call $var3.ContainsKey(\"IsDisposed\")\r\n ) {\r\n .Try {\r\n $var1.IsDisposed = (System.Boolean).Call Simple.Web.CodeGeneration.PropertySetterBuilder.SafeConvert(\r\n ($var3.Item[\"IsDisposed\"])[0],\r\n .Constant<System.RuntimeType>(System.Boolean))\r\n } .Catch (System.Exception) {\r\n $var1.IsDisposed = .Default(System.Boolean)\r\n }\r\n } .Else {\r\n .Default(System.Void)\r\n };\r\n .If (\r\n .Call $var3.ContainsKey(\"TestProperty\")\r\n ) {\r\n .Try {\r\n $var1.TestProperty = (System.String).Call Simple.Web.CodeGeneration.PropertySetterBuilder.SafeConvert(\r\n ($var3.Item[\"TestProperty\"])[0],\r\n .Constant<System.RuntimeType>(System.String))\r\n } .Catch (System.Exception) {\r\n $var1.TestProperty = .Default(System.String)\r\n }\r\n } .Else {\r\n .Default(System.Void)\r\n };\r\n $var1\r\n}"
scopeBlock =
[0]: {(Param_0 = value(Simple.Web.Ninject.NinjectContainer).BeginScope())}
[1]: {(Param_0 = {var Param_1; ... })}
[2]: {Param_0}
[3]: {(Param_0 = Create(Param_1, Param_2))}
[4]: {Param_0}

Update; posted message to Ninject google group with mono runtime trace.

Fixed by using Mono-specific version of Ninject with conditional reference. In upcoming pull-request.
