I think you are having session problems, like the session is not there on the
next click.. You are running one app server (tomcat?) with no load balancer,
or multiple tomcats with sticky cookie load balancing, right? Which version
of app server? How did you install it?

So I blew away my grouper.ui install and redid it. The only config change I
made was to set the grouper.folder attribute in Same
result. (Is there some other configuration that I should be changing that I
have missed?)

I do get the error described if I login and go straight to a group, click
"Add members" and search. I checked the html of the page before submitting
the form and there is a <input type="hidden" name="newSearch" value="Y"/> tag
in the form.

Also, on the page to add a folder I'm filling in all three fields: Folder
name, Folder Id, and Description.

Thanks for your help.
