Hi Vadim and other Mewa users

Actually I answered your question about Mewa in Seaside 2.5 already 
some days ago but somehow the mail didn't get into the list...

You can get Mewa for Seaside 2.5 here: 
http://kilana.unibe.ch:8888/Mewa/Mewa.Seaside2.5.al.13.mcz. Though, one 
thing is not working properly yet: The editor for multiple 
relationships. (I just haven't had time to figure out how I can easily 
implement the newly added requirement to return the collection of child 
components). But apart from this it should be working. Let me know if 
you have problems.

I am not sure if Mewa should go into Seaside at this moment. I have 
been using it in two projects now (one with many forms and the other is 
SqueakSource). For a third project Mewa would not have been of big 
value because we had a lot of very specialized forms. So, Mewa may be a 
good solution for one project but not for another.
Concerning further development, I think that making the rendering more 
customizable would be valuable to explore. At the moment, the default 
visitor which renders the editors generates html tables and if you like 
to change the layout you have to make subclasses. A solution might be 
giving the renderer layout policies that define how to render the 

Feedback would be very welcome!
