Hi All,
i'm trying to get the new ZK Spring 3 samples from ZK Spring Essentials / Inject Components in Spring Beans running, but it seems i missed something.
When i try to access the ZUL, i get an error that tells me that it was not able to map the ZUL-Components to my spring composer class:
SEVERE: Servlet.service() for servlet zkLoader threw exception

From what i understand the mapping from the composer-bean to the window is working, but it fails to map the window components back to the composer. Where can i start looking to find my issue?
Thanks & Bye,

Hi Christian,
Please use Textbox ZK component instead of Textbox interface i.e.
import org.zkoss.zul.Button; import org.zkoss.zul.Textbox;
import org.zkoss.zul.api.Button; import org.zkoss.zul.api.Textbox;
Asish:
We were using ZK 3.0 to solve a ConcurrentExceptionProblem (we have changed some mails about this) ZKSpring new version solve this issue but there is no possibility now of wiring non-ZK POJOs using @Autowired annotation.
Is this a known limitation? In that case wich is the best place to put SpringUtil.getBeans(...) sentences in order to obtain such POJOS?
Thanks a lot
Regards,
Bruno
Hi Bruno,
Sorry to hear that you are still facing some issue with ZK Spring. If you take a look at custom scopes example from ZK Spring Essentials in that a non-ZK POJO SimpleMessageBean is wired using @Autowired annotation in the composer.
The only difference between wiring non-ZK POJOs and wiring ZK components is that ZK components are lazy initiated i.e. when the very first time composer/controller is requested any ZK compoents wired using @Autowired annotation will be injected with a spring proxy where as all other non-ZK POJO wihin the same controller/composer are injected based on their own configuration so I don't see autowiring of ZK components affecting any other non-ZK POJO injection.
In the mean time I am pretty sure you know this but still want to mention that for @Autowired to work bean package has to be mentioned in the <component-scan/> element of your spring config file.
Otherwise I would appreciate if you could provide me some example that demonstrates this issue then I would be happy to investigate it further.
Hi Ashish,
I send you the login.zul and LoginComposer.java files that correspond to a login that is not working. The access (Acceder) button doesn't seem to send any event because method in the composer does not execute. Can you help us to solve this?
Thanks for your help!!!
Juan

Hi Juan,
Thanks for the test code. Greatly appreciated. Unfortunately it is a bug and I have posted it to ZK Spring issue tracker here. I'll fix it and have a freshly release. I'll notify here once it is ready for download.
Hi all,
I am new with zk and spring. I am getting this ugly error when trying to run this example
