I also see this issue in 6.4. For embedded components, the style option
will show up, yet when I go to choose a style, it will not persist. (It
blinks briefly with the correct style, then the page refreshes) However,
it does store the proper cq:styleIds information. Any idea how I can get
the class to persist and make the style system work as expected for
embedded components?smacdonald2008
