I think mainclass *must* be a subclass of MovieClip in as3compile.
Why? I don't know.
It seems to me that the -M arg is ignored.

if you run swfdump on the resulting swf where the mainclass is a
subclass of Sprite, you have:
[HEADER]        File version: 9
[HEADER]        File is zlib compressed. Ratio: 77%
[HEADER]        File size: 367
[HEADER]        Frame rate: 25.000000
[HEADER]        Frame count: 1
[HEADER]        Movie width: 400.00
[HEADER]        Movie height: 400.00
[045]         4 FILEATTRIBUTES as3
[052]       324 DOABC
[04c]         5 SYMBOLCLASS
                exports 0000 as ""
[001]         0 SHOWFRAME 1 (00:00:00,000)
[000]         0 END

Look the line that says:
exports 0000 as ""


And now running swfdump in the resulting swf where the mainclass is a
subclass of MovieClip, you have:

[HEADER]        File version: 9
[HEADER]        File is zlib compressed. Ratio: 77%
[HEADER]        File size: 391
[HEADER]        Frame rate: 25.000000
[HEADER]        Frame count: 1
[HEADER]        Movie width: 400.00
[HEADER]        Movie height: 400.00
[045]         4 FILEATTRIBUTES as3
[052]       341 DOABC
[04c]        12 SYMBOLCLASS
                exports 0000 as "Sitemap"
[001]         0 SHOWFRAME 1 (00:00:00,000)
[000]         0 END

Now look to the "exports" line, you have your "Sitemap"

Yep, this one is OK

Yes, I get the same behaviour.


I have attach a possible solution for this.
With this you can have a Sprite as mainclass.
I don't know if this patch will raise others issues. Matthias???
