We agree it's a must, and do recognize the lengthy delay this has gone through. We sat down last month and began implementing the features we wanted, mainly to allow posting multiple types of activites that happen in JomSocial to the user's Facebook wall. Unfortunately, when we first scoped out the work and planned for it, we were planning to use the onBeforeStreamCreate plugin call of JomSocial. According to the documentation on JomSocial's site, that should have sent our plugin the activity name, what would go to the wall, and other useful bits of information. Upon testing though, it rarely was fired with the proper information, and most of the time fired with none of the information.
The doc page for the call is below, but JomSocial's documentation pages are acting strange lately saying they're not the most recent.. but then redirecting to the same page:
www.jomsocial.com/docs/Event:_onBeforeStreamCreate
So, the bad news is that, yes, we've hit another stumbling block, and need to investigate further. The good news is that this is now becoming one of the higher requested features as others have been tackled since the original request. Still not sure how we're going to do it (there are some other 'hooks' we can use, but not nearly as clean as onBeforeStreamCreate would have been). The last thing we'd want to do require any code changes to JomSocial to call our code.
Just wanted to give status on this in that it hasn't been lost or forgotten, just not nearly as easy as we once hoped.
