Subject Re: Ajax libraries: let's wait a bit
Date Tue, 08 Nov 2005 06:07:51 GMT
Hi Sylvain and other AJAX gurus ;-)

I wonder, if you heard of Taconite [1] which seems to have released 1.0 
It is licensed under the Apache License, but I don't know, if it does 
what we need.

Additionally to the list of AJAX libraries already posted [2] I found an 
other one in [3].
But unfortunately Taconite isn't mentioned in both lists.
