I created about a dozen custom alert templates that we plan on using across several sites. I then proceded to create the alerts for the individual lists within the site. All was going fine up until I tried to change the alert template from the WSS default one to one of my custom ones when I get this error message: Only PickerDialog types can be used with the dialog. The type should be configured as a safecontrol in this site.
Anyone see this message before? Any assistance would be helpful.
