[jira] [Created] (WICKET-3854) Not all IComponentConfigurationBehavior methods are called

Not all IComponentConfigurationBehavior methods are called
----------------------------------------------------------

                 Key: WICKET-3854
                 URL: https://issues.apache.org/jira/browse/WICKET-3854
             Project: Wicket
          Issue Type: Bug
          Components: wicket-core
    Affects Versions: 1.4.17
         Environment: Windows XP Professional 2002 SP3 German
            Reporter: Christian Huber


I implemented a subclass of IComponentConfigurationBehavior and added this behavior to a component in my application. Unfortunately not all of the callbacks provided by the interface are called during building and rendering the component. 

When adding the behavior to a subclass of the Link component only the following methods are called: isTemporary, bind, isEnabled and detach

When adding the behavior to a Label instance getStatelessHint is also called.

But callbacks like beforeRender, afterRender, onConfigure etc are never called.

I created a quickstart to show this effect, when running the example Start class and accessing the page with a browser the default quickstart page gets shown. The label has a behavior attached that writes a line to System.out for each invocation of one of it's method simply showing the methods name.

Igor Vaynberg resolved WICKET-3854.
-----------------------------------

    Resolution: Invalid
      Assignee: Igor Vaynberg

your test behavior returns false from its isEnabled(Component) method, thus all the relevant methods are not called on it.
