Re: Anonymous classes and restoreComponentState Exception

[Dennis Byrne]

Is it trying to instantiate a BasePageBean directyly? I noticed that class is abstract?

Hi everybody,

First of all, thank you very much.

One thing to remember, this application is actually running
correctly with Sun reference implementation, I'm not using
any of MyFaces particularities.


Here goes the full stack trace, and some code snippets:

java "Pages" are managed-beans with managed-scope -> Request.
