I have a situation where I need to colorize an image using image.colorize = "#RRGGBB", but only after a call has been made to the server to find out what color the image needs to go. When I use the same piece of code in _createView or _updateView works perfectly, but when I place it in the callback from loading data, the image disappears. Is this a known bug?
Nope, definitely not a known bug. I'd need to see a code snippet at minimum to be able to help further. Please either email firstname.lastname@example.org or post here in the forums.
I've seen this "colorize bug" myself whenever I dynamically change the colorize value of an image. The 1st time I set the colorize value of an image the colorizing works properly, but the next time I change the colorize value the image appears all black. I have had to resort to removing the image, and re-appending each time before I apply a colorize value. While this gets around the issue, it is not ideal.
