I have the same problem that Mike described (about a year ago). The solution offered by Peter Breis, "The style you have selected when you click on the Update button is the one all the text of that style will be updated to" is not helpful to me because:
- if I select text that is styled as desired ('Heading 2' in my case), the 'update' button does not appear. This is as expected, the text matches the defined style.
- if I select text that isn't styled properly (in the Format/Text sidebar it indicates 'Heading 2 *', the Update button DOES appear.
But I don't want to update the style, I wish to update the selected paragraph WITH the (already correct) style.
If, in #2 above, instead of clicking 'Update', I re-select the desired style name, it fixes that instance. But I have to find and change every 'broken' instance - this defeats the purpose of styled text!
The expected behavior is that when I have text selected and 'Update' the style, all other text with that style should be updated accordingly. If it worked that way, I wouldn't have to attempt to fix other instances of that style with #2 above (I say 'attempt' because doing #2 above simply changes the style definition to that of the text ISN'T styled properly.
It worked as expected in earlier versions of Pages '09, under Lion.
