Logger in page-scoped component, NPE in post-back.

[tazo]

I have page-scoped seam-component with @Logger field and i'm getting NPE then i use logger during jsf post-backs. After debugging i found what log field of LogImpl which is transient does not restored after object deserialization, readObject method of this class is not called.

Right, you should not declare the Log field transient, it is injected at bean instantiation time, logging has nothing to do with Seam bijection!

Sory for my bad explanation, i will try again:
1. @Logger inserts instance of org.jboss.seam.log.LogImpl in a field of my component (lets name it 'mylog', not marked as transient)
2. LogImpl class has field log marked as transient.
3. After postback, 'myname' is restored, but it's LogImpl.log field does not restored: i see null in my debug window.

So i looked at implementation of LogImpl class: log field is initialized in ctors and readObject. Nor ctors, nor readObject() are called in postback, i think it is bug.

LogImpl has the following method:

void readObject(ObjectInputStream ois)
 throws ClassNotFoundException, IOException
 {
 ois.defaultReadObject();
 log = LogFactory.getLog(category);
 }

Are you trying to tell me that Java serialization is broken?
