[Chameleon] JSAPI newbie questions

[Paul Spencer]

Ken,

the CWCJSAPI widget is more or less broken for any version after 1.0.6 
(i.e. any of the 1.1 or 1.99 versions) up to and including the 1.99 beta 
1 version.  It should work for the beta 2 version which is to be 
released this week (pending internal qa review) for most widgets, but it 
likely still has problems that won't be fully resolved until beta 3 or 4.

I would appreciate it if you do try to use it for your project once beta 
2 is released as this will give me some real feedback :)

Cheers,

Paul
