The original design in struts-chain did not contemplate the complexities required to support file upload at all. If you can refactor the existing code to support that gracefully support both use cases, that's awesome ... if it requires separate chains for the two use cases, that's ok (indeed, that's part of the reason that refactoring the request processor into a chain makes things easier to customize).
I went ahead and committed my changes, which don't use subchains, so that people who are looking to switch to using the Chain processor will have working file uploads. We can always refactor later.
I'm extremely happy with where struts-chain is going. I'd encourage anyone with the hacking spirit to start trying it sooner than later and help us figure out if there are any other major features missing.
