[Extendflash] Problems with ComponentInstance.parameters

[John Deans]

Thanks for this. Unfortunately, I can't - as soon as I try to access the
property (even with typeof), my script exits without tracing or alerting
any kind of result. The reason I know it exists is that I can do a
for...in... loop through and read the names of ComponentInstance's
properties - but that's as far as I can go with this particular
property.
 
If anyone has had a similar problem and has overcome it, I'd like to
know. Meanwhile, I think I'm going to add a dummy parameter so that my
array has at least got something in it. 
 
Grr... anyone know if Flash 9 is going to have improved JSFL stability/
bug tracking?

it's an empty array, or undefined, or something else. Has anyone any
ideas? (I'll be happy with any solution that allows me to ignore clips
which don't have parameters defined on them).


Try using "typeof( blah )" to see if it exists, before trying to do
anything else. This returns a string like "number", "object", or
"undefined". This might give you enough information to back off before
trying to do something that will cause the script to fail.

A couple of gotchas here: typeof frequently returns "object" when you'd
expect something more specific, including for arrays and (most
importantly!) null. But "undefined" is always a distinct value, and may
be just what you need here.
