Feature-wise, the work proposed by Edy is very good. In short, it turns XEM
into a tool that can be used to easily manage wiki-based communities, which
is a feature that I see users requesting a lot these days. People I talk
with keep asking me about social and communities in XWiki and I've seen
several workaround implementations on projects I'm involved with already.
Thus I'm very much in favor of making them available in XE 3.2, especially
given that Edy spent a lot of time working on them to have them ready for
the release.
I agree that his solution is far from clean, but we're still waiting for a
clean IX mechanism that I do not believe will be ready for 3.3. Thus this
means that waiting for the IX mechanism to make the Workspaces feature
available would delay it by about 6 months. I'm not in favor of this
solution.

I don't like this too much for 2 reasons:
1) the workspaces app is not part of the platform ATM. It would be like 2) it keeps adding kludges instead of finding a
real solution
To help with point 1), we could vote the fact that we're ok to have
workspaces
in the platform but that doesn't solve 2).
We could look at it point by point and find a solution for each point.
IMO ATM you should use jsx to add those entries so that no change is
required in
the platform. I know some of you don't like this solution but
IMO the best right now when the application is not part of the platform.
Then we need to open a discussion for adding extension points for each
location
where you need it.
One solution would be to use XClasses to provide extension points.
Point 1: Ability to add User tabs. There are several ways in which this
can be
achieved.
Example solution: Introduce a UserTabClass and
add as many tabs as there
are UseTabClass objects in the wiki
Point 2: Ability to add menu entries in the top level menu.
Example solution: Have a MenuEntryClass and a MenuItemEntryClass, each
having 2
fields: one field for the menu entry name and one for the position.
The construct the menu dynamically
The issue with these solutions is performance. A solution would be to add
a module
and have java listener listening to object changes + an API to
return the data. However this maybe slightly too complex. BTW it could be
interesting to offer a generic script service to do this (the idea would be
to offer an active cache that would refresh when an XObject is updated).
Of course another solution would simply be to bite the bullet and start
implementing IX… ;) (I need to read again Sergiu's design doc about it since
I have forgotten how Sergiu planned to implement it)
The major blocker for me is the raw velocity parsing done on the .vm
templates. One step forward would be to implement support for any kind
of templates for generating the response, using the full power of the
rendering engine. But that's something for another thread.
Any other idea?
Accept Edy's patches as a temporary solution, pushing for a proper
cleanup in the next releases.
I don't know how urgent these changes are, we should decide together if
it's OK to skip these changes for 3.2 and instead work on a more
flexible way of integrating them in 3.3.
Thanks
