When I used Group Peer Review end of February, I had no problems.
In May I upgraded the Dataform module to version 3.0.4. The version of Dataform view dataformfield_dataformview is 2.8.6 2014111006

When I try to enter the review page in a GPR activity, I get the following error:

Notice: Undefined index: individualized in /home/pibceduc/public_html/mod/dataform/field/dataformview/classes/dataformview.php on line 232
