[gradebook2-dev] FW: Gradebook Issue

Fri Oct 8 16:06:15 PDT 2010

Jeremy,

We just added a patch to:

http://jira.sakaiproject.org/browse/GRBK-665

... it changes the minimum version from 8 to 7 for removing the cache
directives. Could you please test this in our DEV environment? Also, could
you please send us the request information in a case where you see this
error occurring for  IE 8. We tried several systems that have IE 8 and we
cannot reproduce this problem. Meaning our code in:

https://source.sakaiproject.org/contrib//gradebook2/trunk/server/src/java/org/sakaiproject/gradebook/gwt/sakai/rest/resource/Export.java

removes the cache directives. Any help/information that you can provide is
greatly appreciated.

Best,
-- Thomas
