Explorer.IsProxyLoaded returns false for loaded proxy-Lists...

[Silber_Felix]

I have an entity with children declared like this:

[Entity]
TChild = class;

[Entity]
TEntity = class
private
  FChildren: Proxy<TList<TChild>>;

  function GetChildren: TList<TChild>; // Result := FChildren.Value;
  procedure SetChildren(aValue: TList<TChild>); // FChildren.DestroyValue; FChildren.Value := aValue;
public
  constructor create... // inherited; FChildren.SetInitialValue(TList<TChild>.Create);
  destructor destroy; override; // FChildren.DestroyValue; inherited;...

  property Children: TList<TChild> read GetChildren write SetChildren;
end;

after fetching a single Entity and put my Childrens-list into a TAureliusDataset, accessing my property Children IsProxyLoaded returns false...

bIsLoaded := Explorer.IsProxyLoaded(hEntity, Explorer.GetAssociationByPropertyName(TEntity, 'Children')); // returns false...

I'd like use this for my corresponding ticket refresh lists without generics to avoid fetching datas that are not necessary yet...

Note that Loaded might be false if there is nothing to "load" (i.e., no controller is available).
For example, if you have just created a new entity that was not loaded using a manager.

Yes, I already recognized this point, but in my case I just used fetched entities...

in a shortened way I do this:

hEntity := Manager.Find<TEntity>(1);
TMSLogger.Info(hEntity.Children.Count); => proxy is loaded
bIsLoaded := Explorer.IsProxyLoaded(hEntity, Explorer.GetAssociationByPropertyName(TEntity, 'Children'));
TMSLogger.Info(bIsLoaded); => output is false...

I'm afraid you will have to send us a reproducible case so we can check what is going on, exactly.

[Silber_Felix]

as usual, in my small sample project it is working fine...

[Silber_Felix]

finally I found it...

As I wrote before, I'm using this using recursion on EntityManager.Refresh...
refresh lists without generics

The described shortened way looks like that in real:

hEntity := Manager.Find<TEntity>(1);
TMSLogger.Info(hEntity.Children.Count); => proxy is loaded
**Manager.Refresh(hEntity); // this for sure kills IsProxyLoaded...**
bIsLoaded := Explorer.IsProxyLoaded(hEntity, Explorer.GetAssociationByPropertyName(TEntity, 'Children'));
TMSLogger.Info(bIsLoaded); => output is false...
