VerifyError: Error #1025 or Error from hell

with one comment

i was trying to read an XML with namespaces and then Flash throw me this weird error

VerifyError: Error #1025: An invalid register 3 was accessed

then we found that was beacuse of these lines (locally declared in a function)

1
2

var ns = ttXML.namespace();
default xml namespace = ns;

the error comes when you try to call some function after those lines in your code

the solution that we found was declare ns variable outside of the function
and then everything works fine =D

SoundItem Class

with one comment

well we start with this Sound Util, just embed the SoundTransform and SoundChannel in one single Class and the fade ability (uses Tween Lite)
