I'm planning to start a web based stock and current managament project.
I want app to be Ajax but I don't want to spend my time for client-side code.
Thus, I think to use coolite for my presentation layer.
However, before starting project I want to hear some advices about it.
Is it worth using in a big project and do you have any other advice about this issue?
This would be much better asked on the Coolite forums where you'll hear from actual users of the framework rather than people who will just knock it because it's not jQuery (sigh). IMHO, it is a pretty solid framework -- however, I've never used it in a production app. You really should spend some time evaluating it yourself -- take a day and mess around with their samples and see if you can build something simple. Ultimately only you can decide if it will work for your needs.
