Yes, it does seem a little weird hacky way to do things.
I'm using C2 to display image search results. Ive got everything working with the search request, Ajax loading the results into a dictionary and rendering the results to different visual structures on screen.
The only issue i have is to use the "load from URL" on the sprite object the animation frame needs to already exist. The maximum number of search results is 500 so at the moment it seems like i need to create a sprite with 500 frames to allow me to dynamically load whatever search results come back.
Hacky - yes. But other benefits of C2 make up for this little issue :)
Any ideas how to do it better?
