We tackled in-place edit in the latest screencast in our free Learning Rails course:
www.BuildingWebApps.com/learningrails/14
We were surprised to find that the in-place edit plugin in the official Rails repository still hasn't been updated to be functional with Rails 2, and that it doesn't support several of the options in the Scriptaculous code that it wraps.
We worked around these issues in the screencast, but it was messier than we expected.
If you've been struggling with in-place edit, you might find the screencast helpful.
if you know of a simpler way to handle this, or of any news about the updating of the plugin, we'd really appreciate any feedback.
Thanks,
