Hey terrytornado,

thanks for the welcome and especially for your example. I've downloaded

Another question of mine: Is there something like a global scope for the Composers?
I will try to explain it a little bit more in detail, because I'm not really sure, if it's a "ZK problem" or in general with Java WebApps.

I'm coming from PHP (regarding websites) and started with regular Java Desktop Apps without frameworks a while ago.
Starting with ZK and trying to use Spring Beans, I thought about how do you combines this with different .zul-Files and different composern.

Let's say I have 5 DAOs and 2 Controller handling these DAOs. To create these beans in combination with data source access, I want to use Spring.
Trying to encapsulate every component with an own .zul and composer, how do I access these beans from every composer?
Normally you use AppContext.getBeans only once when starting the application, don't you? But I can't define all composers as a bean in order to get the controllers inside of the composers defined. So instead of calling getBeans only once, I would have to create an AppContext and call "getBeans" it in every composer, wouldn't I?

If I design my page completly with ajax requests, your approach of a HashMap transfering the indexController object to it's "child" objects, looks like a good idea, but calling getBeans() for the controllers is still needed.

Is there somewhere a mistake in the explaination?
How to handle this ZUl - Composer - Controller - DAO reasonable?

Thanks in advance! :)

best regards.

Hey,

thank you really much! Your example files in zkSample and your short introduction here helped me really much!
For everybody else who is still asking, how to do this with maven:

1) ZK maven project is already defined
2) add Spring dependencies: org.springframework.spring-webmvc < This should include nearly everything is needed: http://books.zkoss.org/wiki/ZK%20Developer%27s%20Reference/Integration/Spring#Copy_Spring_binaries_into_your_Web_library
Do steps "Configure web.xml" and "Create Spring Configuration File" of Spring-integration page.
4) create Zul-File & apply controller like mentioned from TerryTornado. Add Variable Resolver from Spring!!!!!

That should be it.

@TerryTornado / anybody:
>Here< I read, that you should use this way, which you explained and works for me. I only used zkoss & spring web mvc dependencies, so currently no ZK Spring dependencies. Should I install ZK Spring? Do I have to change something afterwards like ContextloaderListener -> CoreContextListener, or are there just other scopes avaiable and I should use scope="component" instead of prototype?

Perhaps another question: I just skimed through the explaination of an MVVM approach, so perhaps my question is silly and not useful, but anyway:
Would it be possible to use this dependency injection also in MVVM approach? Can I still use the {bean} notation ?
Something like:

viewModel="@id('vm') @init('{bean}')">

This is nonsense because bean would have already bean initiated, but I hope you know what I mean.
I got this question by asking myself, which composer you should use in which case, so if you have a link for that too, I would really appreciate that!

best regards,

Thanks again terrytornado,

i didn't mean "Spring Utils" but "ZK Spring" (the addon from zkoss), aber anyway, it worked now in a good way.
Your second way with SpringUtils should also be the solution for MVVM, so on @Init(), call it and fill in your beans manually - that should work fine.

Perhaps my last question: In your example, you don't use "SelectorComposer". What's the reason to you to use only GenericForwardComposers? Does SelectorComposer have anything disadvantages (for you)?

best regards

Hey,

because I can't edit my post due to a small textarea window which isn't scrollable, I had to produce this new entry:

During my tests in Tomcat, I always get the info:

org.zkoss.zkex.init.WebAppInit init:-1
Problem: This is an evaluation copy of ZK EE and will terminate after sixty days from the first date of installation. Should you require an open source license or commercial license for ZK EE please contact us at [email protected] for more information. Alternatively you can download ZK CE which is licensed under the LGPL.

I used the ZK EE before, but I removed the 2 jar-files zkex and .. don't know the other one anymore to get back to CE, like another topic here sugggested. Did I miss something?

Thanks in advance!

best regards

Hey,

no no, not "GenericComposers" but GenericForwardComposers :). Because you "only" used GFComposers in zksample2 and no SelectorComposers. That's what I meant :)

Regarding your example: In your webapp/index.zul, your window & borderlayout have height: 100%;
If you only do a small example:

<zk>
<borderlayout>
<north>Test></north>
<center>Center</center>
<south>South</south>
</borderlayout>
</zk>

Why doesn't it work without height specification? height="100%" like your index.zul doesn't work either?!

And last question:
Is it possible if I have <div id="myDiv"> to access #myDiv in Css?

Thanks in advance!
