UPDATE. Sorted that out now, it should have been ErrorMessageResourceName property and not ErrorMessage.

Hi everybody,

All of the sudden I started to get the following error:

Both ErrorMessageResourceType and ErrorMessageResourceName need to be set on this attribute.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

[InvalidOperationException: Both ErrorMessageResourceType and ErrorMessageResourceName need to be set on this attribute.]

In the model it's defined as

 [Required]
        [RegularExpression(SysManagerConstants.PASSWORD_REGULAR_EXPRESSION, ErrorMessage = "passwordInvalid", ErrorMessageResourceType = typeof(Messages),
            ErrorMessageResourceName =null)]
          
        [DataType(DataType.Password)]
        [Display(Name = "newPassword", ResourceType = typeof(Labels))]
        public string NewPassword { get; set; }

So I just added the ErrorMessageResourceName attribute to the RegularExpression but I don't know what should I set it to. I found this question

http://stackoverflow.com/questions/2347650/how-to-use-dataannotations-errormessageresourcename-with-custom-resource-solutio

but I am not sure I understand what Daren meant in that sample. .NET documentation as usual doesn't provide any examples of usage.

So, I am a bit lost of what should I use here as my name of the resource.
