[jira] Created: (WICKET-2479) NPE when clearing DateTimeField

NPE when clearing DateTimeField
-------------------------------

                 Key: WICKET-2479
                 URL: https://issues.apache.org/jira/browse/WICKET-2479
             Project: Wicket
          Issue Type: Bug
    Affects Versions: 1.4.1
            Reporter: Esko Suomi
            Priority: Blocker


This bug is apparently caused by regression of some sort since this was fixed for 1.4.0 (see links below). Simply, the NPE still occurs when clearing the DateTimeField. In our environment we're using CompoundPropertyModel as model object for the related form. When I get back to work (it's saturday so that'd be a few days) I can paste the stacktrace but I doubt that's needed, this should be easy to fix based on information in the previous issues.

Since fixing of this bug has obviously failed before, I've set the priority of this one to Blocker to enforce its quick resolution.

[jira] Commented: (WICKET-2479) NPE when clearing DateTimeField

Posted by "Esko Suomi (JIRA)" <ji...@apache.org>.

Esko Suomi commented on WICKET-2479:
------------------------------------

Interesting side effect I just noticed: Clearing another datetimefield invalidates current session.

[jira] Updated: (WICKET-2479) NPE when clearing DateTimeField

Posted by "Esko Suomi (JIRA)" <ji...@apache.org>.

     [ https://issues.apache.org/jira/browse/WICKET-2479?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Esko Suomi updated WICKET-2479:
-------------------------------

    Description: 
This bug is apparently caused by regression of some sort since this was fixed for 1.4.0 (see links below). Simply, the NPE still occurs when clearing the DateTimeField. In our environment we're using CompoundPropertyModel as model object for the related form. When I get back to work (it's saturday so that'd be a few days) I can paste the stacktrace but I doubt that's needed, this should be easy to fix based on information in the previous issues.

Since fixing of this bug has obviously failed before, I've set the priority of this one to Blocker to enforce its quick resolution.

EDIT: Here's the stacktrace:

[jira] Commented: (WICKET-2479) NPE when clearing DateTimeField

Posted by "Juergen Donnerstag (JIRA)" <ji...@apache.org>.

    [ https://issues.apache.org/jira/browse/WICKET-2479?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12758172#action_12758172 ] 

Juergen Donnerstag commented on WICKET-2479:
--------------------------------------------

According to http://svn.apache.org/viewvc/wicket/releases/wicket-1.4.1/wicket-datetime/src/main/java/org/apache/wicket/extensions/yui/calendar/DateTimeField.java?view=annotate  (which is what was included in the 1.4.1 release)  the line causing the NPE is 

239 : ivaynberg 672603 		setDefaultModelObject(date);
 
This very same line was in 1.4.0 at the very same position.

This line obviously cannot cause an NPE. If the NPE happens inside setDefaultModelObject(date); the stacktrace would include the method.

Are you sure you are using 1.4.1 and not any other older version or maintenance release?

> This bug is apparently caused by regression of some sort since this was fixed for 1.4.0 (see links below). Simply, the NPE still occurs when clearing the DateTimeField. In our environment we're using CompoundPropertyModel as model object for the related form. When I get back to work (it's saturday so that'd be a few days) I can paste the stacktrace but I doubt that's needed, this should be easy to fix based on information in the previous issues.
> Since fixing of this bug has obviously failed before, I've set the priority of this one to Blocker to enforce its quick resolution.
