Let me see if I understand what is going on here...
The dataChange event will only fire if the component is being used as
an itemrenderer, otherwise, the mediaObject will be set in the usual
way...?
We're dispatching a mediaObjectChanged event here, and I'm not sure
why. What is listening for it? Or is it just good practice in case
something wants to listen for it?
The last question I have is about repositioning the image. My
understanding is that the problem is actually the position of the
image within the 100% image control. So since the control is 100%,
I'm not sure how it _could_ be repositioned. Or, are you saying not
to set the image control to 100%?
Thanks!
