Hi Molinari,
 
It will be possible in DevForce6.0.8 coming up this week:
 
aPredicateDescription = PredicateBuilder.Make(typeof(Person), "Person_Profile.Id_Person_Profile", FilterOperator.IsEqualTo, QueryOperation.Person_Profile.Id_Person_Profile);

Regards,
   Silvio.

Hi,

I have one problem in execute this query with predicate

_em.Person.Where(f=>f.Person_Profile.Id_Person_Profile == 1); to works perfectly....

but i trying using with predicate....

public void Get(Person QueryOperation)
{

List<PredicateDescription> predicateDescriptions = new List<PredicateDescription>();

PredicateDescription aPredicateDescription;

if (QueryOperation.Person.Person_Profile != null)
{
aPredicateDescription = PredicateBuilder.Make(typeof(Person), "Person_Profile", FilterOperator.IsEqualTo, QueryOperation.Person_Profile);
              
predicateDescriptions.Add(aPredicateDescription);
}

//TODO: execute the query ...
}

then show this error

Unable to create a constant value of type 'Crmall.Entities.Person_Profile'. Only primitive types ('such as Int32, String, and Guid') are supported in this context.

then i change code    

aPredicateDescription = PredicateBuilder.Make(typeof(Person), "Person_Profile.Id_Person_Profile", FilterOperator.IsEqualTo, QueryOperation.Person_Profile.Id_Person_Profile);

then show this error..

Unable to locate property 'Person_Profile.Id_Person_Profile' on type 'Crmall.Entities.Person'.......

Ok... then change code

aPredicateDescription = PredicateBuilder.Make(typeof(Person_Profile), "Person_Profile.Id_Person_Profile", FilterOperator.IsEqualTo, QueryOperation.Person_Profile.Id_Person_Profile);

then show same error

Unable to locate property 'Person_Profile.Id_Person_Profile' on type 'Crmall.Entities.Person_Profile'.......


then ideabladeTeam is that possible ?

thanks...
