It's ok, I think I figured it out. The attribute is not available on the client
side. Within the generated
code for the class, it was missing the TermCustomValidation class and it has
the following
message. So now I just have to figure out why the class isn't coming across to
the client.
T.
// Unable to generate the following attribute due to the following error(s):
//
// - The attribute
'System.ComponentModel.DataAnnotations.CustomValidationAttribute'
references type 'Brightstar.SSP.Web.Shared.TermCustomValidation' that is not
accessible in the
client project 'Brightstar.SSP.csproj'. Are you missing an assembly reference?
// - The attribute
'System.ComponentModel.DataAnnotations.CustomValidationAttribute'
references a method 'EnsureTermCategory' on
type 'Brightstar.SSP.Web.Shared.TermCustomValidation' that is not accessible in
the client
project 'Brightstar.SSP.csproj'.
// [CustomValidationAttribute(typeof
(Brightstar.SSP.Web.Shared.TermCustomValidation), "EnsureTermCategory",
ErrorMessageResourceName = "TTermCategoryRequiredError",
ErrorMessageResourceType =
typeof(Brightstar.SSP.Web.Resources.ValidationErrorResources))]
