Although I've yet to look at this closely, based on a current widget we have installed (will try and update name to give them the credit) I think it may be possible to create a helpdesk by by-passing the frog database system. I don't want to spend too much time on this as rickyjamesb states they are planning to improve this and have noticed that they seem to be developing the fdp site.
The basic concept will be to create a helpdesk call (creates a folder and container page) for a problem, then states overall details (creates 1st page within the the call folder that will be shown on container page) then multiple comments for feedback (create more pages that will be added to the container page). When the job is done, the folder/pages can be marked as expired.
This would definitley be a work around solution and not ideal as providing functionality to search a knowledgebase and the volume of folders created may be an issue. Personally I think the benefits should outweigh disadvantages, but this will have to be tested.
I hope to look at this in the short term future and will post any progress.
