Hi All.
I have never worked with ZK, so I cannot really comment on it. I do know it
has a very good reputation and competes in the same space with the GWT. See
this link:

YUI is a little different. It is purely a front-end technology (JavaScript,
CSS) whereas ZK and GWT are both front-end and server side. Rocky is correct
in that ZK and GWT may have you buy into a particular architecture. On the
other hand, YUI leaves the server-side up to the developer (i.e. implement
the JSON, and other low-level stuff).

There are a lot of great choices out there.

I like YUI a lot and have used it successfully.

Hi Jon,

I have some experience with ZK, although it has been at least a year since I
have used it.
I'll briefly give some pros and cons based on my experience:

Pros
--The XML markup they use for building the GUIs is great for rapid
prototyping
--The toolkit of widgets is rich and continues to grow
--Much of the behind the scenes wiring is done for you
--The end product looks great

But...
--The framework is not designed to work with existing web applications.  In
other words, you have to commit to the whole thing or nothing.
 Additionally, it would be hard to plug in only a piece of ZK into an
existing application.
--Because so many details are abstracted, it can be hard to know what's
going on behind the scenes, and therefore hard to do any custom
functionality.


For these reason, Curator decided to go with YUI from Yahoo.  Working with
YUI does take a bit more time, but in my opinion it gives more complete
control over the behavior of the widgets and the AJAX requests, etc.  Also,
you can take only a single YUI component and add it to an existing
application.

So if your needs are to build a quick web app from scratch, then ZK could
very well be the right way to go.  However, if you need fine-grained control
of widgets or need to slowly evolve an existing app, I would check out YUI.
 Also, unless you are web UI expert, the ZK app will likely look more
polished than an app built with YUI.  If you really need to impress someone
with a sexy UI, then ZK should be among your top choices...

Julien Chastang is very familiar with YUI and similar toolkits, so he might
have additional comments...
