hi,

i want do this

Public Function CheckEntity(ByVal _entity As EntityBase, ByVal _id As Object) As Boolean Dim col As EntityCollectionBase col.EntityFactoryToUse = _entity.EntityFactoryToUse Dim filter As PredicateExpression filter.Add(PredicateFactory.CompareValue(_entity.Fields(0).FieldIndex, ComparisonOperator.Equal, _id)) col.GetMulti(filter, 1, Nothing, Nothing, 0, 0)

    dim fk as object = col(0).Fields(1).CurrentValue 

End Function

but the filter doesn't work. it won't even compile.

basically the function gets an id and some empty entity object. and i want the real entity

is this possible?

With compile errors, it's helpful to mention the error here so I can help you better

Your code doesn't work because you try to instantiate an abstract class (EntityCollectionBase), which doesn't work of course.

id is the primary key field value?

What you need is also the name (or index) of the field which is the ID. If that's always index 0, you can do: _entity.Fields(0).CurrentValue = _id _entity.Refetch()

ok, but then i get the error

The field is marked readonly and cannot be changed.

otherwise it would be brilliant

Ah, it's an identity field then. Do instead: _entity.SetNewFieldValue(0, _id) _entity.Refetch()

erm, i still get the same message.

i do hope i don't have to change it in the designer. i use the selfservicing-template btw.

Sorry, my bad. (mondays)...

_entity.Fields(0).ForcedCurrentValueWrite(_id) _entity.Refetch()
