Hi Sowmya,

There are the standard hook methods:

The method wdDoInit() is called immediately after the controller has been instantiated. Preparatory work should be performed in this method.

The method wdDoExit() is called immediately before the controller is garbage collected. You should write code to perform clean up tasks in this method.

The method wdDoPostProcessing() is a hook for error handling during context validation.

The method wdDoBeforeNavigation() is a hook that allows you to implement your own navigation processing if you want to override the standard navigation.

The method wdDoModifyView() is called immediately before a view is rendered. This is the only place where you can to modify the viewu2019s UI elements.

Thanks,

Hi,

I believe you may be referring to "hook methods". These are methods executed at specific events in the life cycle of a WDJ application on the server.

Their names and formal parameter are predefined by the framework when you create a WDJ Component.
