Currently java serialization api totally ignores readObject methods of
serialazable seam component itself and any of it fields type. Simple test case:
| package demo;
|
| import java.io.IOException;
| import java.io.ObjectInputStream;
| import java.io.Serializable;
|
| import org.jboss.seam.ScopeType;
| import org.jboss.seam.annotations.Logger;
| import org.jboss.seam.annotations.Name;
| import org.jboss.seam.annotations.Scope;
| import org.jboss.seam.log.Log;
|
| @SuppressWarnings("serial")
| @Name("transientTest")
| @Scope(ScopeType.PAGE)
| public class TransientTest implements Serializable {
|
| @Logger
| private Log log;
|
| private transient String message = "initial";
|
| public void testSeamLog() {
| log.error(message);
| }
|
| public void testTransientField() {
| message.equals("restored");
| }
|
| void readObject(ObjectInputStream ois) throws ClassNotFoundException,
| IOException {
| ois.defaultReadObject();
|
| message = "restored";
| }
|
| public String getMessage() {
| return message;
| }
| }
|
|
And test page:
| <?xml version="1.0" encoding="UTF-8" ?>
| <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
