I have made a translation in spanish for SparkWeb. I could use it with the svn version of Sparkweb and it work almost fine. There something that are not translated, but it 's a less, and there is not defined in locale file.
I don't have too much experience with FlexBuilder (a few with eclipse and this have make it so easy), but i couldn't find a way to define what locale properties file i were to use, so for practical reasons i compile changin the original en.properties with the spanish properties. (does someone know?)
I think that it could be usefoul for someone else, so i let here the file.
PD: sorry for my english, i'm not native speaker.
