I'm pretty sure this is happening because you're using SMW 1.0 pre-alpha; Semantic Forms doesn't yet support SMW 1.0. I'm marking this as a duplicate of bug #11204.

Thank you for your quick response!

Could well be as you say. We are using pretty current svn revisions, both updated yesterday early night. (Should not trunk branches be stable and fit together?)

Anyways, is there a known revision of both SMW and SF, going together, that we should be using best atm?

Is there an estimate available as to how long it will take for SMW 1.0 + SF be available and rather stable? just roughly thinking of days/weeks/months/next year, so as to adjust our various scheduled tasks accordingly, if possible.

We have made additional sf language files. Is it OK to commit them, or do you want them reviewed before?

Yes, I agree that main trunk branches should be stable and fit together: you should tell that to the SMW developers, who are putting their unreleased, unstable code in SVN. :) Though, to be fair to them, the MediaWiki SVN system, which is what we're both using, doesn't allow for multiple branches, so they didn't have much of a choice.

If you use use SMW 0.7 instead, which is available for download from the Semantic MediaWiki site, and is what they recommend for downloading, everything should work fine.

I have no idea when SMW 1.0 will become the stable official version. The developers haven't said anything. I'm guessing another two or three months, but that's just a guess. I'm also guessing that Semantic Forms will support SMW 1.0 by the time that happens.

Yes, feel free to just commit the language files, no review necessary. Thank you very much!

Ok, thanky you, that helpes us a lot!
