Hey!
I have two polygons (from a shape file) which share an edge, i can render
each one perfectly (left image side). Now i'd like to render this 2 polygons
as one polygon (right image side). Would this be possible using some special
SLD filter? Or is this not possible at all.

Not possible at all, SLD does not alter the geometric nature of the
data. If you need that, you'll have to use some other tool to merge the
polygons (postgis has merge functions for example, so you could eventually create a view that does the merge on the fly).

I see, i was expecting something like that 
This seems like something that could help with the problem. What's the
status of this?

As you can see the page is 3 years old. It's the first time I see
it actually, so I can assure you that thing is dead.
We're considering adding the ability to specify a query to
build a new feature type for JDBC databases, but it's not trivial
and we have no one sponsoring/working on it so it won't be done anytime
soon.
The good news is that you can buid a view in your database and then
you can treat it like any other feature type, so you don't actually
need the above.
Cheers
Andrea

Yes, i saw that it is 3 years old, that's why i thought that something has
been done in this area. I guess i'll check out the views.
Thanks for the info Andrea!
