Subject [jira] Updated: (SHALE-220) init() lifecycle method called twice
Date Fri, 29 Sep 2006 12:14:25 GMT
     [ http://issues.apache.org/struts/browse/SHALE-220?page=all ]

Bob Butash updated SHALE-220:
-----------------------------


I have an issue that is similar to Shale 220 (http://issues.apache.org/struts/browse/SHALE-220).
 I am using Shale version 1.0.3 and for normal View/ViewController processing the init method
is only being invoked once.  However I have a subview that has a ViewController backing bean
associated  with it.  The sub view's init call back method is being called twice.  Is this
a known issue, and is there any way to prevent it.

> 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

> ==========
> 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.
