{null} is generated for most symbols (Even symbols that could be documented properly before.)

[bausshf]

I'm unable to generate proper documentation right now, which causes a lot of symbols to generate {null} as the return type.

When generating the documentation I get the following errors:

Finished parsing docs.

Let's just look at an example like this:

Function diamond.controllers.basecontroller.BaseController.mapAction has non-fun
ction type: Primitive

It generates this:

final {null} mapAction ();

Previously it has been able to generate it correct like this:

final void mapAction ( 
  diamond.http.method.HttpMethod method, 
  string action, 
  Action fun 
);

See here

This is the actual definition in the source file:

    /**
    * Maps an action to a http method by a name.
    * Params:
    *     method =    The http method.
    *     action =    The action name.
    *     fun =       The controller action associated with the mapping.
    */
    void mapAction(HttpMethod method, string action, Action fun)
    {
      _actions[method][action] = fun;
    }

So what's the issue here? Why can it suddenly not generate documentation properly after certain changes/additions in the source code?
