Content load failes for dynamic modules with hierarchical st - Sitefinity - Front- & Back-End Development

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.

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?
