问题
I would like to use OmniFaces ListConverter as my converter on PrimeFaces autocomplete.
Unfortunately the following exception pops out when I tried to.
As far as I'm concerned, JSF converters are not required to implement Serializable interface. I read the java ee 6 tutorial and was unable to find such a statement.

I had the feeling that MyFaces is trying to unserialize any object used on my page. How can I handle that situation?
Environment
- WebSphere Application Server 8.5.5.2
- Apache MyFaces 2.0.2
- OmniFaces 1.7
- PrimeFaces 5.0

import javax.inject.Named;

回答1:
This is a bug in MyFaces. I can't tell which MyFaces version exactly contains the fix, but I can tell that this construct works fine in at least MyFaces 2.1.12. However, upgrading MyFaces in WebSphere might not be a trivial task (technically and bureaucracy).
Your best bet is to tell MyFaces to not serialize the whole view state in session, but instead keep it in memory and hold a reference (like as Mojarra by default does). You can do that via the following context param in web.xml:
<context-param>
<param-name>org.apache.myfaces.SERIALIZE_STATE_IN_SESSION</param-name>
<param-value>false</param-value>
</context-param>
