DataBinding Injection

[calderas]

Sorry for my inexperience.

I'm using Errai DataBinding as Standalone module and it is working fine.

Now, I want to replace the manual set-up by Injection (@PostConstruct, @Inject, @Bound, @AutoBound, tec.), but it is not working.

I already added the empty file ErraiApp.properties and the default beans.xml with bean-discovery-mode="annotated".

Thanks a lot,

Juan

Hi Juan,

In previous posts, you wrote that you want to use Errai DataBinding as a standalone library since you didn't want to use other Errai libs. But now you want dependency injection which of course requires IOC.

If the latter is the case now you will have to inherit either the errai-ioc or errai-cdi GWT module. You then no longer need the manual bootstrap logic described here: https://developer.jboss.org/thread/254203

Cheers,

Christian

Hello Christian,

Yes, I guess I have to include "on demand" more Errai modules.

For many months Errai caught my attention but I was hesitant to include it in my development in order to avoid another layer, framework, etc; however, I'm finding that it is easy, stable and others advantages.

Thanks for your help.

Juan
