There are no proxy providers registered yet.

Hello Together

We got this error when we execute a rpc call (no difference between Caller<RPCInterface> and MessageBuilder) in a @PostConstruct method for example. I have tried to debug and determine the problem and it seems to me, thats the rpc proxies are registred after the initial execution of the entrypoint. But i'm not really familiar with the exactly boostrap process.

I get exactly the following exception:

ERROR: Unable to load module entry point class org.jboss.errai.ioc.client.Container (see associated exception for details)

I can also reproduce this in a new created project with the cdi-quickstart archetype ... adding a RPC Service and acces this one in the @PostConstruct method of the entrypoint. I have attached the project.

Make i anything wrong, or has anyone a suggestion to solve this problem?

Thanks in advance.

Edit:

- This error comes up in version 2.1.0.Final and 2.1.1.Final on JBoss AS 7.1.1.Final

I found a solution take works.

As Mike Brock mentioned in a other thread "InitVotes.registerInitCallback(Runnable)" ... works perfectly for this problem.

Thanks!

Hi Michel,

Yes, the InitVotes system is the way all the subcomponents of ErraiBus keep track of whether or not they are initialized. You are certainly free to use this system in your app.

There is also a declarative facility based on InitVotes: annotate any method in an ErraiIOC or CDI bean with @AfterInitialization, and it will be called once all the init votes are in.

Hope that helps,

Jonathan

Hello Jonathan

Thanks for that input! This annotation is very useful.
