Ok. This just popped up today.
 
After I create a new entity, which also creates an associated entity, I then modify the data. For my GUI, devex grid, I force validation using VerifierEngine.Execute on the entity. It passes. Then I go to save and it fails stating that validation failed.
 
To try and find the issue, thinking it may be mis-match of manager, I ran FindEntities on the manager that have been modified, added, deleted. This returns the entities I created. I then looked at each entity and the values where present that were failing validation.
 
Basically, all looks well but it is still failing during save for validation.
 
Please help!!!!!!!!!

We rerun the validation on the server as an additional security check before saving.  I'm guessing that one of your custom verifiers is a little more unusal and doesn't like being run on the server (e.g. you might have problems creating another EntityManager on the server).  If you need to, you can suppress server-side validation by overriding EntityServerQueryInterceptor.ValidateSave() and not calling the base class implementation.

That isn't something I want to do. The verification and save work fine on a modified objects. Just not a new objects. Why would that be?

I'm not sure.  Can you remove the verifiers one by one to isolate the one that is failing for the new objects?  We could then look at the code that fails.

It is the same verifier. Checking that the length of the string is atleast 1 character and sends a specific message. I tried a few different methods but they didn't work as I wanted. The message was never correct. So I did it this way.
 

public class MinLenghtStringVerifier : StringLengthVerifier

    {

        public MinLenghtStringVerifier(System.Type pType, string pProperty, string pMessage, int pMin, int pMax)

            : base(pType, pProperty, true, pMin, pMax)

        {

            this.VerifierArgs.ErrorMessageInfo.ErrorMessage = pMessage;

        }

    }

Any suggestions? See anything in that wouldn't run on the server?

No, that looks pretty simple.  I saw that you'll be working with someone in our services group.  You can have them take a look, or if you can reduce it to a simple test case, open a support case and send the zip.

Hello, is this issue being solved.

I've seem to have a  similar problem.

 

Whatever I do, the error result is always the default generated message  ‘Name is Required’

Tried different verifiers.

Only a VerifierDelegate seems to work (I find a VerifierDeletage a bit overkill for just adding localization)

 

public class VerifierProvider : IVerifierProvider

{

   public IEnumerable<Verifier> GetVerifiers(Object pVerifierProviderContext)

   {   List<Verifier> verifiers = new List<Verifier>();           

       verifiers.Add(new RequiredVerifier("Contenttype required a unique name."));

       return verifiers;

   }

}

           

          

private class RequiredVerifier : RequiredValueVerifier

{

    public RequiredVerifier(string strMessage) : base( typeof(ContentType), ContentType.EntityPropertyNames.Name)

    {   this.VerifierArgs.ErrorMessageInfo.ErrorMessage = strMessage;

    }

}

My problem was that I was performing validation from  another object. So, when a record was changed for one object it was validating a child object as well. Apparently it doesn't allow this.

Ok, thanks.. my problem is a bit more straightforward.

I still do not understand why my custom message isn’t showing.

 

In short,... how do I localize my validation message?

 

-          Can find anything in the DF2010 developer guide.

-          Can find any examples of  VerifierEngine.ErrorsResourceManager

 

I’ve read something about silverlight validation Exception versus Validation Notifications.

But not yet understand the issue on the subject.

I made a post on localizing verification error messages here:
http://www.ideablade.com/forum/forum_posts.asp?TID=1964 - http://www.ideablade.com/forum/forum_posts.asp?TID=1964
 
Hopefully, that will be enough to get you started.
