Model has value even when null is passed to view through controller

Question

I am using Glass mapper for mapping Sitecore item to class objects.

In one of the module when I pass null to a view, The model still has a value. It seems like it is inheriting page properties. Below are screenshots.

Screen shot 1: Passing null value to view

Screen shot 2: Model in view still has a value

Below is the code for Related_Content that is generated by TDS:

/// <summary>
/// Related_Content
/// <para></para>
/// <para>Path: /sitecore/templates/User Defined/PokerCentral/Component Templates/Data Templates/Callouts/Related Content</para>    
/// <para>ID: 2b54f9fd-1fb5-4638-98b0-0acd420c5b81</para>   
/// </summary>
[SitecoreType(TemplateId=IRelated_ContentConstants.TemplateIdString)] //, Cachable = true
public partial class Related_Content  : GlassBase, IRelated_Content
{

                    /// <summary>

            public virtual IEnumerable<Guid> Item_Listings  {get; set;}

            [SitecoreField(IRelated_ContentConstants.TitleFieldName)]
            public virtual string Title  {get; set;}

            [SitecoreField(IRelated_ContentConstants.Base_CategoryFieldName)]
            public virtual Guid Base_Category  {get; set;}

            [SitecoreField(IRelated_ContentConstants.Base_TagsFieldName)]
            public virtual IEnumerable<Guid> Base_Tags  {get; set;}


}

Can someone let me know how can I fix this?

You have to try to change the name of your object. I already see this problem. The mapping do something magical and maybe try to get any information for the property in some cache or something like that. — dpfauwadel
Object name which is "Related_Content" in my case is generated from TDS(Team Development Server). In such case how can I change the name and more over we need a Model of type "Related_Content" passed to view. — Akhil
@AhmadHarb I have updated my question with "Related_Content" code. Please verify. — Akhil
@Arjun can you try to pass Cachable = false in the SitecoreType attribute, it has nothing to do with the passed value of the object but let's give it a try. — Ahmad Harb

You are inheriting from GlassView<Related_Content> Glass loads the model automatically if your rendering is on context item.

If you want to pass the model from controller don't inherit from Glass view instead use @model Related_Content

By looking at your code, your are passing data source to your view. if you are inheriting from Glass View, It will loads the data source into the model.

Model has value even when null is passed to view through controller
