TypeError: Error #2007: Parameter bitmap must be non-null.
at flash.display::Graphics/beginBitmapFill()
at noponies.display::NpTileBg/resize()

Luckily, I figured it out. I solved it by wrapping the 2 addEventListener statements inside the addedToStageHandler function in an: if(obj is BitmapData){ } block. Then I added the same 2 addEventListener functions to the loaderComplete function so that if you’re loading an external image they’re only added once the bitmap is finished loading. Seems that the Event.RESIZE was calling the resize() function the moment it was added for some reason, well before the HTTP bitmap had a chance to load, therefore screwing up in the resize() function.

Hope that helps. Thanks again!

My computer crashed this week and I had to reinstall Flash and rewrite my project, but it seems to be ok now! Still don’t know why I got this error… Sometimes computers lead a life on its own

Sorry to have bothered you with this, anyway thanks for your help!

For instance, if its in your library, it needs to be passed to the class like this;

NpTileBgInstance.newBgTileImage = new Header(0, 0);

Header is the export for ActionScript class name of the bitmap in the library.

If you check the online demo, I’ve changed it to use a library bitmap for the second tile.

Thanks for your time, I’m working with CS3 and Flash player9, could this be the problem? Maybe just a bug in Flash…
