but to the original question ;) you don,t need <ui:text> markup at all :). ui:text element has been introduced because you could not use {messages.messageKey} in plain text not as attribute. as title is an attribute it is not needed in that case.
just write: <span title="{msg.yourTitleMessage}"><ui:text from="{msg.someText}" / ></span> -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
