Answer: B A. Replace the defaultValue=”0″ attribute of the ‘charLimit’ field in the dialog with min=”0″. (min property is for minimum value allowed) B. Add the @Default annotation to the ‘chatLimit’ variable in the Sling Model. (Correct Answer) C. Replace the defaultValue=”0″ attribute of the charLimit field in the dialog with defaultValue=”{Long}0″. (No such property called defaultValue) D. Change the defaultInjectionStrategy of the Truncation Sling Model to DefaultInjectionStrategy.REQUIRED. (@Optional annotations are only evaluated when using the defaultInjectionStrategy = DefaultInjectionStrategy.REQUIRED (which is the default), )

The default value is set using 'value' property, NOT 'defaultValue'. Here @Default will work
