Sorry for that delay. I'm really interested in look through the component and ideally as a result put it into the 4.x but unfortunatelly can't access neither the svn you mentioned nor the sample. Could you please add more details on how to check it?
My domain master was temporarily down. It is already up.
Hey, that is really cool, and I'd love to take a closer look as well.
I curious what the dependencies would be for this.
Client side uses jQuery plugin called jCrop.
Server side is just a component based on RF3.3.3.Final.
The component itself does not crop. It just returns selection coordinates (as java.awt.Rectangle, maybe it should return something different, but it is easy to change).
So good news: this component does not have any heavy dependencies.
The problem with usage for attribute for connection the cropper to the image could be seen if click to reRender the image. And b.t.w. could it be pointed to a few images at time? If this not supported and not planned to be like that - probably could just implement as "a4j:support" to be inserted as a image child in order not to have such problems.
In general - cool one! I believe should be ported to 4.x!
