DynamicImageResource in ajax panel
I have a panel that I update via ajax.
In that panel is an Image.
The Image uses a DynamicWebResource, whose getImageData() method produces a
PNG file.
The getImageData() override gets called the first time the page renders but
upon subsequent refreshes of the panel via ajax, it does not... so my image
doesn't get updated.
I've tried marking it as non-cacheable and I also tried invalidating it...
but nothing seems to cause the getImageData() override to be called again...
any ideas what I might be doing wrong?
TIA
