Vaadin Migration from 7 to 8

Hi,
After the changes am getting the below exception:

Caused by: org.jboss.weld.exceptions.DefinitionException: Exception List with 1 exceptions:
Exception 0 :
[CDIUI_WITHOUT_UI]
 Inconsistent deployment: The non-abstract class com.shaic.***
with @CDIUI should extend com.vaadin.ui.UI
	at com.vaadin.cdi.internal.VaadinExtension.throwInconsistentDeployment(VaadinExtension.java:93)

Error seems to say you have the @CDIUI annotation on a class that does not extend UI. Is this the case?

Yes,import com.vaadin.cdi.CDIUI;

No, I mean, which class do you have the @CDIUI annotation on? You should have something like this:

@CDIUI("myui")
public class MyUI extends UI {
    ...
@CDIUI
public abstract class GBaseTable<T> extends ViewComponent {
	
	}

Ok, then that is your problem. Like the error message says, the @CDIUI annotation should only be placed on a class that extends UI. You have the @CDIUI annotation on a class that extends ViewComponent, which I assume is not a UI.

Hi,

Now we are facing the below exception,

SEVERE [com.vaadin.server.DefaultErrorHandler]
(default task-8) : java.lang.NullPointerException
at com.vaadin.cdi.internal.AnnotationUtil.getUiBeans(AnnotationUtil.java:80)
at com.vaadin.cdi.CDIUIProvider.getUIBeanWithMapping(CDIUIProvider.java:176)
at com.vaadin.cdi.CDIUIProvider.getUIClass(CDIUIProvider.java:118)

Kindly suggest.

So what does your @CDIUI-annotated class look like now?

We are now using @CDIUI anotation only for classes that extends UI

Hi,

Now we are facing the below exception,

SEVERE [com.vaadin.server.DefaultErrorHandler]

Kindly suggest.

Kindly update.

There has been some API and usage changes between 2.0 and 3.0 versions of the CDI add-on.

I have one demo app which covers most of the cases how to use 3.0 with Vaadin 8 https://github.com/TatuLund/cdi-demo

Hi,

Thanks,We will check and update.

Hi,

The below exception message
com.vaadin.cdi.internal.AnnotationUtil.getUiBeans(AnnotationUtil.java:80) at

shows me that BeanManager is null, when i debug. Is there any way to make sure
BeanManager is available and instantiated???

Any Idea on this

From AnnotationUtil.java

public static Set<Bean<?>> getUiBeans(BeanManager beanManager) {
       // The annotation @CDIUI can have a value, so using it as the type
       // parameter of AnnotationLiteral is somewhat problematic.
       Set<Bean<?>> uiBeans = beanManager.getBeans(UI.class,
               new AnnotationLiteral<Any>() {
               });
       return uiBeans;
   }

any update on the issue?

Is there any way to make sure BeanManager is available and instantiated???

Bean manager is setup by the container, e.g. Wildfly, so if it is not there, something has gone wrong earlier in the startup of the app. You may find hints by reading the log.

Also did you remember to add beans.xml https://github.com/TatuLund/cdi-demo/tree/master/src/main/webapp/WEB-INF ?

I have followed the below document, added the Default and alternative annotations into more than one classes which are implemented the same interface. Also, added alternative entries in beans.xml file and still getting same error. If an interface implemented in only one class, Should I mark Default annotation for that too? Please advise.

The documentation you linked is for Vaadin 14

The documentation about Vaadin 8 version of CDI add-on is here: https://vaadin.com/docs/v8/framework/advanced/advanced-cdi.html

Normaly you do not need to add anything to beans.xml

Okay! Let me check and revert you back.

Regarding annotation they have mentioned in Version 8 also.
https://vaadin.com/docs/v8/framework/articles/IIInjectionAndScopes.html

As per documentation “The application should not have a servlet extending VaadinServlet, as Vaadin servlet has its own VaadinCDIServlet that is deployed automatically.” https://vaadin.com/docs/v8/framework/advanced/advanced-cdi.html)
Changed VaadinServlet to VaadinCDIServlet and application working fine now.
public class CreateIntServlet extends VaadinCDIServlet {
public class MSServlet extends VaadinCDIServlet {
