Transparency zero= Bugs?

Getting Started Newbie Questions
#1

I think I have found a bug. When you created a circle in version 1 of charts: 

Display.newCircle NuevoCirculo = (622,215,30) 

and was assigned … color and transparency: 

NuevoCirculo: setFillColor (255,0,0,0) 

The circle is red, but not seen. Well, the last value is 0 (zero). Here comes the problem. If you used the circle as a button to trigger an event, the circle despite being invisible was active. If you played on the circle shooting an event. It turns out that since version 2.0 graphics, if the circle is invisible can not trigger an event. 

I want to know why? 

Display.newCircle NuevoCirculo = (622,215,30) 

NuevoCirculo: setFillColor (1,0,0,0)

If you want invisible objects to receive touch events you can use object.isHitTestable = true. http://docs.coronalabs.com/daily/api/type/DisplayObject/isHitTestable.html

Hope that helps.
