Set the userSession member, generate a Log Id, set the requestHandler, and validate the component's configuration. NOTE: this method has several side effects not related to validation. could probably use some refactoring

Specified by:

validate in interface IUIComponent

Parameters:

session -

actionRequestHandler -

Returns:

boolean true if component configuration is valid, else false
