Stephan - I don't understand this, but hopefully you do. :)

Could you please explicitly identify which version of SF you are running? Because this sounds like a bug fixed more than 6 months ago.

I used the GIT HEAD versions by 2013-12-02 for MediaWiki, Semantic Wiki, Semantic Forms, etc.

Sergey - are you sure about that? I just looked through the code history, and as far as I can tell the call to serialize() in SF_FormPrinter.php was commented out in May 2013:

https://git.wikimedia.org/commitdiff/mediawiki%2Fextensions%2FSemanticForms.git/ca8d126424c19df723c0f8d39bc6ca21cb49be5c

Maybe you're on some tag/branch and not aware of it? What actual version of SF are you running? (See Special:Version.)

I'm setting this to "invalid" - I simply don't see any way that this could be due to anything other than using old code.
