But as far as I can see, I am not a Javascript prof
I try to use Flexigrid in very special project that doesn't cry really for such a advanced application (a lot of database tables depending on each other). But I see it as a "skill enhancement" and I am able to spend some time with this brand new things (javascript, jquery, flexigrid). And I am still impressed, all this enhanced clientworking... The return of the fat-client, cool. I do not expect it in a browser, but it is really fun.
When it is all done I can buy Paulo a Coffee on my company's bill %-P
