I was trying to run a rule with a Data Transform included to run during the creation of a page. So i checked "Apply data transform" in the Run Record window and added a data transform. However, every time i ran the rule, the message "Apply data transform failed. Unable to find Data Transform named <rulename>" was returned. It seems that there is a WHEN rule missing in 'pzCreateOrResetTestPageInNewThread'. When I do a private edit and remove this line, all works fine and the data transform is applied. Pega bug? (the problem still occurs in Pega 8.6)
