  - ### Method Detail

    - #### getText

          public static String getText(String key,
                                       String defaultMessage,
                                       List<Object> args,
                                       ValueStack stack)

      Get a message from the first TextProvider encountered in the stack. If the first TextProvider doesn't provide the message the default message is returned.

      The stack is searched if if no TextProvider is found, or the message is not found.
      Parameters:
        `key` - the message key in the resource bundle
        `defaultMessage` - the message to return if not found (evaluated for OGNL)
        `args` - an array args to be used in a `MessageFormat` message
        `stack` - the value stack to use for finding the text
      Returns:
        the message if found, otherwise the defaultMessage

    - #### getText

          public static String getText(String key,
                                       String defaultMessage,
                                       ValueStack stack)

      Get a message from the first TextProvider encountered in the stack. If the first TextProvider doesn't provide the message the default message is returned.

      The search for a TextProvider is iterative from the root of the stack.

      This method was refactored from `Text` to use a consistent implementation across UIBean components.

      Parameters:
        `key` - the message key in the resource bundle
        `defaultMessage` - the message to return if not found
        `stack` - the value stack to use for finding the text
      Returns:
        the message if found, otherwise the defaultMessage
