Hi Feri,

You can't use injected comonents during a constructor.

(The reason being, there is technically no instance yet for the interceptors to inject the dependency into)

So,

You need to move any work with injected dependencies into a method annotated with @Create, as this is run after the constructor, when the interceptors can get to your instance.

I haven't looked at your code in any depth, but try this for example.

public SaHome() { // setDaId(..) moved to onCreate() } @Create public onCreate() { setSaId(new SaId()); }

Hope this helps,

Rob

Sorry, that code example was clearly awful, I'm sure you'd have worked it out but this is better:

public SaHome() { // setSaId(..) moved to onCreate() } @Create public void onCreate() { setSaId(new SaId()); }

Hi Sir Rob,

I already Try as you told me before, but when i run the project error come :

Caused by: java.lang.IllegalStateException: component has two @Create methods: <component name> at org.jboss.seam.Component.scanMethod(Component.java:677) at org.jboss.seam.Component.initMembers(Component.java:552) at org.jboss.seam.Component.<init>(Component.java:244) at org.jboss.seam.Component.<init>(Component.java:205) at org.jboss.seam.init.Initialization.addComponent(Initialization.java:1186)

I try to find in forum too about this error and i found link like this :
component has two @Create

Could you help me?

Thanks u so much

Feri,

in your object's inheritance

Home \ \ EntityHome \ \ SaHome

Home already has the @Create annotation in use, but (if you look at the source) it is kind enough to offer you a method you can override during this process.

@Override public void create() { super.create(); setSaId(new SaId()); }

.... should do the trick!
