How can I get Three20 TTStyledTextLabel to work with external images?

I found an old entry in the Google 320 group about support for an external image that was not yet implemented, but some months ago, and it looks like TTStyledText is trying to support external images in new versions.

I pull out my hair, trying to understand why it does not work me. To reproduce, you can change the sample text in TTCatalog / StyledTextTestController.m points to an external image, not a bunch of image. Upon exiting, I see that the image is actually being downloaded over the network and after downloading, calls TTStyledText styledTextNeedsDisplay on its own (TTStyledTextLabel), but the display is not updated to show the new image.

If I close the application and reload it, the image will be loaded properly from the cache, but it never works when it needs to load it in line. Has anyone found a solution to this problem?
