Just checked out the zf incubator code because I wanted an easy way to add a tag cloud to phplifestream. Instead I ended up hacking around in the code. Guess it is under heavy development still. But I filled an jira issue for it anyway. My patch is available at github if someone else wants to play with this component.
Yesterday I found a bug in the phplifestream when calculating a unique id for the an activity. I fixed this bug but unfortunately this ment that all previous aggregated activities had a different id. Today I rolled back that commit because I think it makes since to keep the previous calculation.
If you where running on the code between those two commits I recommend you to run the following sql queries to remove aggregated activities with wrong unique id.
