Im using FLASH CS3 with AS3
i have a flash project, i separete file swf
ex. main.swf, profile.swf, invite.swf, visit.swf

profile.swf will be loaded in main.swf

Problem:
When load profile.swf in main.swf from a browser, cell renderer failed (data won't show)


Is there an issue with load swf file ??
is bad or good separate swf file??

You need to provide any error messages and relevant code snippets.

I bet it's a security sandbox issue.
You gotta use security allowDomain and crossdomain policy files, because loading swfs is a potentially risky operation
