WizardAction is a special advanced Acttion type used in Wizards. WizardAction is a PopupWindowShowAction descendant. Lets remind, that PopupWindowShowAction is useful when you want a user to input several parameters in a popup dialog before an Action is executed. WizardAction allows to make a number of sequential steps for editing object's parameters. In addition to this, WizardAction allows to pass some steps according to the specific conditions.
