Help: stuck trying to make a new console object...

This isn't really a bug... it's more of a gap in my understanding...

I'm trying to create a new object like a t2dStaticSprite. It took the t2dStaticSprite.h and .cc files and made copies of them as t2dText.h and .cc. I went through and made the necessary renames and eliminated the datablock portion. I just want a dynamically createable console object based off of t2dSceneObject. At this point, everything compiles and still works. Now's when things get a little wonky:

I start messing with the parameters to ConsoleMethods... like I get rid of the ConsoleMethod for setFrame and getFrame, and change the signature of setImageMap from being:

ConsoleMethod(t2dText, setImageMap, bool, 3, 3, "(imageMapName$, frame) - Sets imageMap and frame.")

to

ConsoleMethod(t2dText, setImageMap, bool, 2, 2, "(imageMapName$) - Sets imageMap.")

I went through this function and eliminated all references to frame. Now when I run my code, I can never get voltage across this console method. Instead, I just get an error in the Console window that says:

t2dText::setImageMap - wrong number of arguments.
usage - t2dText::setImageMap - (imageMapName$) - Sets imageMap.

Is there something magical I should know about creating or tweaking a ConsoleMethod? Here's the source code to my current version of the method:

ConsoleMethod(t2dText, setImageMap, bool, 2, 2, "(imageMapName$) - Sets imageMap.")
{
   // Set ImageMap.
   return object->setImageMap( argv[1] );
}
