----------------------------------------------------------------
So far we have in my opinion three possibilities
1: We file an issue in weld itself and propose that this ejbRef can be
serialized, but then it may be that the glassfish proxy that followes is not
serializable and we're back on field one.
2: We propose (as described in the seam-wicket guide) the workaround that all
injected ejb fields must be transient, and that in the onattach hook the
members are injected again. The downside is, that this code must be inserted on
every component/page.
3: We use Wicket-ioc an wire a serializable proxy between the injected ejb and
the field.

> EJB and Seam Wicket result in NotSerializableException

>
> Key: SEAMWICKET-41
> URL: https://issues.jboss.org/browse/SEAMWICKET-41
> Project: Seam for Apache Wicket
> Issue Type: Enhancement
> Affects Versions: 3.0.0.Final
> Environment: Wicket 1.4.17, Glassfish 3.1 and Glassfish 3.1.1
> Reporter: Thierry Peng
> Fix For: Future
>
> Original Estimate: 1 day, 2 hours
> Remaining Estimate: 1 day, 2 hours
>
> Injection of EJBs with Seam for Apache Wicket does not work properly. Wicket
> tries to serialize all injected references once the page/component changes
> its version. The culprit is the
> org.glassfish.weld.ejb.SessionObjectReferenceImpl.ejbRef which is not
> serializable, see the forum reference for the stacktrace.
> There are few discussions about this problem, one mentioned, that the spec
> doesn't require that an ejb must be serializable, which is true. Because this
> is a Problem which mainly affects wicket and its way to serializable the
> component tree, I suggest that we solve it in this module.
