showcase with diffConfig='att' context parameter:
<context-param>
<param-name>org.icefaces.diffConfig</param-name>
<param-value>att</param-value>
</context-param>

TextEntry, TextAreaEntry, AutoCompleteEntry, ComboBox > Indicator Text: once the validation ace:message's are rendered on page, the required indicator text can no longer be updated in the h:inputText required text, and therefore on the ACE input component. (diffConfig='att' specific) . If not using the diffConfig='att' the required text can be updated by blurring the h:inputText, and the tests pass.

Steps:
- disable, then re-enable the 'Required' checkbox -> validation messages are rendered on page.
- enter new text for Required Indicator Text, and press 'Tab' or 'Enter' key -> the required text fails to update on page when either blurring the "Required Indicator Text", or when pressing the "Enter" key.
