Hi Craig,

Now that I have subscribed to Shale user group, I am posting this issue again.

Just to make sure that I am not using older version of Shale libraries, I have
downloaded shale-framework-20060713.zip and tried, same problem. This is what I
did, to reproduce the issue in usecases project. ( I am not able to post code
from my project because of lot of dependencies on EJBs/Database)

I downloaded the latest usecases zip (07/14/2006). Unzipped the war file into a
directory, created a project in eclipse, added the java source files, built and
deployed it into JBOSS and it ran fine. Added the following code at the end of
org/apache/shale/usecases/locale/Select.java overriding the "do-nothing" init()
from ActionViewController.

public void init() { System.out.println("Select.java - Init - PostBack Value: " +
Boolean.toString(isPostBack())); }

redeployed and ran. The console output when I click on "Select Language" link

15:20:27,515 INFO [STDOUT] Select.java - Init - PostBack Value: false 15:20:27,515 INFO [STDOUT] Select.java - Init - PostBack Value: false

and on sumbit (when I click on "Go" )

15:20:33,546 INFO [STDOUT] Select.java - Init - PostBack Value: false 15:20:33,562 INFO [STDOUT] Select.java - Init - PostBack Value: true

My environment is :

OS : Windows XP Home JBOSS 4.0.4 Patch1 with Tomcat 5.5 JRE : 1.5.0_06 Eclipse 3.1.1

Thanks Vish

I was able to reproduce this with latest trunk bits, using the default testing
configuration (MyFaces, Tomcat 5.5). It's clearly a bug in how init and destroy
method callbacks are being triggered for view controllers, most likely related
to the fact that the mechanism for this was recently changed.
