I have been having an interesting time over the last few days trying to set-up a Joomla website which has Community Builder as the front end user interface to the K2 extension. Unfortunately the proposed marriage of CB and K2 seems platonic at best.

Originally I wasn't aware that 2 of Community Builder's core plugins, CB Blogs and CB Articles, could actually handle K2 articles but the plugin chapter of the CB Primer manual was quite a revelation. Indeed I quickly configured both of those plugins and can now list articles (that I am the owner of) on the CB profile page with CB Blogs offering additionally functionality in that I both edit and delete K2 items.

However there are a number of issues.
1. The CB user's portrait/profile image is not displayed as the author image in the K2 article. Instead the default black silhouetteis displayed
2. When I edit a K2 item going through the link on CB Profile page (using the CB Blogs plugin), the title alias is changed with "-2" added at the end. As an example, this changes SEF URL
www.*******.co.uk/news/parmesan-smelly-de-normandie-and-stinking-camembert
to
www.*******.co.uk/news/parmesan-smelly-de-normandie-and-stinking-camembert-2

I am fairly sure these issues stem from K2 having it's own user system as I have found, via the magic of Google, other folks having similar problems but nothing recently. This leads me to believe that all these issues have been resolved and it's me who has not set-up his website correctly.

Thanks for replying and after posting my original message, I asked one of my usual freelancers (PHP specialist) to take a look at it and he came up with a code hack as "K2 doesn't handle events". This basically involved changng all the instances within K2 which looked for author image within the K2 user table to instead use the Community Builder table. This works as both extensions have the same user id for that author although it's a hack and not really a long term solution.
