thanks owen, i have been reading through this but my question is one
more regarded to the specifics of display groups. I have found
specific good information on the fetching data section of that guide,
but I don't know how this fits into the display groups as they are
different and I'd like to do the same thing they talk about with
"refaultObject" on the editing context, but I need to this for the
display group ??
Is there just not one simple method to say, "Hey, display group go
refetch all fresh data now, and ignore what cached data is
available" ?? I don't see anything exactly like this in the api for
display groups. Seems this would be pretty simple. Just go get fresh
data when I tell you. Why does it have to be so hidden and complicated ?
qualifyDataSource() doesn't seem to cut it. Why, Why, Why ?? This is
where WebObjects leaves me hanging a bit and I'm sure others have
felt the same..

I am using this to get my display group to refetch and it works
sometimes and other times it doesn't work. Am I doing something
wrong?
displayGroup.setMasterObject(myMasterObject);
displayGroup.qualifyDataSource();
I do not have "Fetches on Load" checked on the display group
configuration because I want to control when objects are fetched.
Basically, I have a display group of comments and every time
someone adds a comment, I would like to save the new comment and
cause the comment list to refresh itself immediately to show the
newly added comment on the returned page with all the other
comments. And sometimes this works and other times it doesn't ???
