CGContextEOFillPath not working .. ?

Hello all.

I want to be able to fill the area  between 2 rects that Im building as following:

-(void)createPath:(CGContextRef)ctx withInnerRect:(NSRect) rect{
	NSRect outterFrame = [self bounds];
	CGContextBeginPath(ctx);
	//Outtter Line
	CGContextMoveToPoint(ctx, NSMidX(outterFrame), NSMinY(outterFrame));
	CGContextAddArcToPoint(ctx,
							 NSMaxX(outterFrame), NSMinY(outterFrame), NSMaxX(outterFrame), NSMidY(outterFrame), 5.0f);
	CGContextAddArcToPoint(ctx,
							 NSMaxX(outterFrame), NSMaxY(outterFrame), NSMidX(outterFrame), NSMaxY(outterFrame),5.0f);
	CGContextAddArcToPoint(ctx,
						   NSMinX(outterFrame), NSMaxY(outterFrame), NSMinX(outterFrame), NSMidY(outterFrame), 5.0f);
	CGContextAddArcToPoint(ctx,
							 NSMinX(outterFrame), NSMinY(outterFrame), NSMidX(outterFrame), NSMinY(outterFrame), 5.0f);  //???#1
	CGContextAddLineToPoint(ctx, NSMidX(outterFrame), NSMinY(outterFrame));

	//Inner Line

	CGContextMoveToPoint(ctx, NSMidX(rect), NSMinY(rect));
	CGContextAddArcToPoint(ctx,
						   NSMaxX(rect), NSMinY(rect), NSMaxX(rect), NSMidY(rect), 5.0f);
	CGContextAddArcToPoint(ctx,
						   NSMaxX(rect), NSMaxY(rect), NSMidX(rect), NSMaxY(rect),5.0f);
	CGContextAddArcToPoint(ctx,
						   NSMinX(rect), NSMaxY(rect), NSMinX(rect), NSMidY(rect), 5.0f);
	CGContextAddArcToPoint(ctx,
						   NSMinX(rect), NSMinY(rect), NSMidX(rect), NSMinY(rect), 5.0f);  //???#2
	CGContextAddLineToPoint(ctx, NSMidX(rect), NSMinY(rect));
	CGContextSetLineWidth(ctx, 3.0f);
	CGContextSetStrokeColorWithColor(ctx, CGColorCreateGenericRGB(0.5f, 0.5f, 0.5f, 0.7f));
	CGContextStrokePath(ctx);
	CGContextClosePath(ctx);
	CGContextEOFillPath(ctx);


}

Sot both rounded rects are being display, dont ask me but for some reason the lines didn't want to go to the end on the lines  //???#1 and  //???#2, and I had to add an CGContextAddLineToPoint, to where the line started. Anyway, I want to fill the are between these 2 rect with the set color, I thought calling the CGContextEOFillPath will just do it, but it seems Im missing something, I was reading the docs but they don't say much about it, just show these images of concentric circles and using the fill methods and thats it.

Any ideas what am I missing in order to achieve the goal.?

Thanks

Gustavo
