LLBLGen default variable field values reads not null but are null

Question

I have an LLBLGen entity.

MyEntity{
    public Decimal Foo;    //Stored in database as a NOT NULL field
}
....
public void SomeMethod(){
    MyEntity entity = new MyEntity();  //on initial inspection Foo reads as "0"

    adapter.SaveEntity(entity);  //will throw exception, "Foo can't be assigned a NULL value"
                                 //but on debug inspection, Foo = 0

    entity.Foo = 14M;
    adapter.SaveEntity(entity);  //will save ok.
}

If I don't assign a value to a number, the debugger reads it as not null, however, it throws an exception telling me that it's actually NULL.

I was trusting LLBLgen to auto assign all variables a default value, but I can't be so sure now.

Anyone able to shed some light on this please. Thanks.

The LLBLGen Pro runtime doesn't assign default values automatically, however you can specify it as default constraints in your database.

You can check if a field has a value assigned by checking the 'Fields' collection on your entity:

bool isValueAssigned = myEntity.Fields[(int)MyFieldIndex.Foo].CurrentValue!=null;
