I have hit this sticky wicket.. I try to export a game via the PhoneGap export option. The target platform is Blackberry (Blackberry7, handset).
A folder is created as expected. Upload to Build.phonegap, the blackberry compile throws an error, about illegal characters in filenames and/or directories. So the exporter creates spritesheets named $spritename-sheet0.png but [._-] etc are illegal characters, according to Phonegap, I assume this is what the error refers to (I already renamed the icon_128.png and edited config.xml accordingly, so thats not it).
How do you guys work around that?
