function OnWizardUpdate () : void

Description

This is called when the wizard is opened or whenever the user changes something in the wizard.

This allows you to set the helpString, errorString and enable/disable the Create button via isValid. Also it lets you change labels (for timers i.e.) or buttons when the wizard is being shown
