Spritesheets are not loading at preload time

In version 2.1.1 of cocos2d-html5 I’m finding that sprites that come from spritesheets do not appear in the game until they have been loaded, even though the .plist files are included in the g_ressources object at initialization time.

When I port the game to 2.1.2 WebGL gives an error because the spritesheets are not loaded yet, and thus their contentSize rectangle is null.

Is there any way to correct this behaviour? I’d like the spritesheets to load at preload time, and not let the game start until the process is complete.

Thanks!

I think you should also preload corresponding png file, but no only .plist file.
