Congratulations!!!!

I mostly agree with Marcos, but I don't expect to be full compatible with version 3.6 because it's a major change. However, I expect to be able to develop for version 5 in the same way, i.e., don't need to handle JS at all, but if I want to, it's easier with zk 5 than 3.

Way to go!!

just send query syntax

Congratulations, it looks very interesting. ZK has been taking some extraordinary strides recently - ZKStudio and Zeta Forms for example.

If I may add a word of caution: I have become disillusioned with open-source projects in the past when they charge ahead, adding new features without ensuring that the existing features are fully debugged and stable. Please don't make the mistake of forgetting about keeping the basic framework quick and reliable!

@Marcos - are you talking about browser memory, or server? I have been very happy with server-side memory usage on 3.6, whereas client-side memory usage is currently (unsurprisingly) highly variable between browsers.

@Andy I'm baffled by what you're asking for - if you want to write SQL queries in your web page. surely PHP is what you're after?!

Great preview! That rocks!

BTW: why do you skip version 4.x ???

As you are moving to LGPL does that mean that you will drop the dual license model. As far as I know LGPL would permit closed commercial ZK based applications, as ZK is more or less a "linked library".

@David: I can confirm that server side memory usage is fair as far as you support just a few 10 to 100 concurrent sessions (single server) and with IE the performance is sometimes pure but it become far better with 3.6.2! But client side memory usage is a nightmare if you have many ui components or if you have to deal with large amount of data.

Congratulations! I really love to see the integration of jQuery. Good move.

@Marcos: I guess the performance issue you referenced is the browser's capability to handle complex CSS introduced since 3.6. I had simplified the theme, and it works really fast.

@ZK: I suggested to have a theme that is less trendy but fast to render. ZK Calendar is a good move -- no background images but div.

@Horst: don't use live data if amount is huge, since listbox will create every listitem for them (even though the real content is not loaded). I solved this by use of an external paging.

I personally really don't like programming in Javascript, that's one of the feature that bring me to use ZK, but i know that some client action are needed in modern web app.
What about a GWT like solution that convert a subset of Java Code to Javascript?

@Madruga: Compatibility in same way you expect: "I expect to be able to develop for version 5 in the same way"

@David and Horst: Until today all my application has no problem related to performance! I would like to see how much memory ZK 5 uses less than previous ZK Version in both server and client side.

One last note, it is better if ZK can upgrade bean shell to version 2 and mvel also to version 2.
