Description

Given a view scoped bean:

@ManagedBean
@ViewScoped
public class Bean implements Serializable {
@PostConstruct
public void pc()

{ System.out.println("in postConstruct"); }

}

and a simple form:

<h:form>
<h:commandLink value="update">
<f:ajax render="label"/>
</h:commandLink>
<h:outputText id="label" value="#

{bean}

"/>
</h:form>

Repeatable hitting on "update" button makes the value of label change:
com.denisk.test.Bean@5b62a166
com.denisk.test.Bean@27afca98
com.denisk.test.Bean@3a93ea5f

PostConstruct is fired only once though.
I know that there is plenty of ViewScoped-related havoc in JSF2, which is described in
http://java.net/jira/browse/JAVASERVERFACES-1492
and related JSF spec issue (which will be fixed in spec v. 2.2):
http://java.net/jira/browse/JAVASERVERFACES_SPEC_PUBLIC-787
But current defect seems to be MyFaces-specific since on Mojarra 2.1.8 this works just fine
