Content load failes for dynamic modules with hierarchical structure

  • Content load failes for dynamic modules with hierarchical structure
  • I have a question about how to get childs for
    a dynamic module.

    The code I have works, but sometimes the content.SystemChildItems
    returns null (for same object). Why is it only loaded sometimes?If I call the
    page 5-6 times, one of them will return null. It does not make sense. Can't I
    trust that the dynamicModuleManager.GetDataItem will load the objects or what
    am I doing wrong?



    Here are some code
    stringproviderName = string.Empty;
     
    DynamicModuleManager dynamicModuleManager =
    DynamicModuleManager.GetManager(providerName);
     
    Type sliderType = TypeResolutionService.ResolveType("Telerik.Sitefinity.DynamicTypes.Model.Slider.Slider");
     
    DynamicContent item = dynamicModuleManager.GetDataItem(sliderType,
    SliderId);
     
    boolchildren = dynamicModuleManager.HasChildItems(item);
     
    if(children)
        dynamicModuleManager.LoadChildItemsHierarchy(item);
        foreach(DynamicContent content initem.SystemChildItems)
        
            // here the content.SystemChildItems is empty sometimes, but not always!
     
            foreach(DynamicContent layer incontent.SystemChildItems)
            
                layers.Add(ParseLayerModel(layer));
            
     
            slides.Add(ParseSlideModel(content));
        
        ParseSlider(model,item);


    I have tried to add this

    boolcontentChildren = dynamicModuleManager.HasChildItems(content);
     
    if(contentChildren)
        foreach(DynamicContent layer incontent.SystemChildItems)
        
            model.ErrorStep += 1;
            layers.Add(ParseLayerModel(layer));
        


    But then contentChilden is ALWAYS (??) false. I don't get it.

    Reference: www.sitefinity.com/.../getting-and-setting-parent-items
  • dynamicModuleManager.LoadChildItemsHierarchy(content);

     

    This did the trick I think

  • Hi Team,

    I have the same issue. But it is not working even after applying your solution.

    I'm getting an exception while loading the function "LoadChildItemsHierarchy"

    Exception is :  "Cannot build a query with DynamicContent type. Actual childType is required."

    I'm passing the parent content item as parameter to the function "LoadChildItemsHierarchy".

    My code is :

    dynamicModuleManager.LoadChildItemsHierarchy(parentItem)

    I have no idea why it is happening. Anyone has any idea regarding why this exception is fired?
