PopupDialog

OK - I used your "How to: Display a List of Non-Persistent Objects " as an example how to do this and now I can display the popup and it contains the list of selected Tasks. But the dropdown of employees is empty. How do I populate it with the employees, stored in the database?
Thanks,

I have solved my problem. The reason for it was that I was using the wrong ObjectSpace: Application.CreateObjectSpace but I needed an objectspace from my module that has a different database.
Thanks again for your excellent support :)

You are welcome!

One more thing regarding this. When I try to pass an employee to the constructor of the non-persistent class as a default value I get the following error message when I open up the dropdown:
An error with number 1021 has occurred.
Error message: The object that has been passed belongs to another ObjectSpace. This error may occur when you manipulate your objects via an ObjectSpace which these objects do not belong to. For instance, you may receive this error when using the XafApplication.CreateDetailView method in case you passed an object that was obtained from a different ObjectSpace than the ObjectSpace used as a parameter in this method. To correct this error, you should ensure that all the objects you manipulate belong to one ObjectSpace.
In most cases, to avoid this error it's sufficient to call the ObjectSpace.GetObject/GetObjectByKey methods to get a passed object in the target ObjectSpace.
I think I understand the problem but I don't know how to solve it as I don't know how to get to the objectspace instance that has populated the dropdown when the object was created.
Thanks,

Hello Ægir,
Please review code in the ObjectSpace GetObject Question thread. As you can see, the GetObject method is used to pass objects from one ObjectSpace to another:

C#
objectSpace = Application.CreateObjectSpace();  
object currentObject = objectSpace.GetObject(View.CurrentObject);  

Please let us know if you need further assistance.

Unfortunately this is not helping as I am working here with a non-persistent class that contains no Session or ObjectSpace objects. I have no idea how the dropdown is populated by the framework.
My class is simply like this:
namespace Syslumenn.Module.Adfarir.BusinessObjects.SyslAdfarir
{
   [DomainComponent]
   public class SetjaFulltrua
   {
       adStarfsmadur fStarfsmadur;
       public adStarfsmadur Starfsmadur
       {
           get { return fStarfsmadur; }
           set { fStarfsmadur = value; }
       }
       StadaAdfaramals fStada;
       public StadaAdfaramals Stada
       {
           get { return fStada; }
           set { fStada = value; }
       }
       private List<AdfaraMal> fMalalisti;
       public List<AdfaraMal> Malalisti
       {
           get
           {
               return this.fMalalisti;
           }
           set
           {
               fMalalisti = value;
           }
       }
       public SetjaFulltrua()
       {}
       public SetjaFulltrua(StadaAdfaramals s)
       {
           Stada = s;
       }
   }
}

Please send me a sample project where this issue is reproducible. I will be happy to research it and provide you with a suitable solution.

Thanks, I have created a new project where my problem exists. Just let me know if this needs further explanation.
Best regards,
Ægir

Thank you for the sample project. I have checked it on my side, and it seems to work correctly. I have attached a video that illustrates it.
Am I missing important steps?

Yes - the error occurs when you open the drop-down for employees.
Best regards,
Ægir
