GetCurrentActualNode returns null

VERSION: 6.1
I am trying to get my custom inbound pipe to search the branch of the tree that the user is currently in. 
My Code is filtering the information thanks to some other threads on here. 
But now i want to get it to use the current node as a reference point. 
the problem is however that the getActualCurrentNode() returns null, actually i have tested getCurrentNode(), getActualCurrentNode.SiteMap, CurrentNode, SiteMapBase.CurrentNode. Nothing is bringing back any results for me. 

Am i coding this wrong? 
This is from my custom_search class  which inherits pageInBound, and the Global.Asax file runs this on application_start. 

PageNode node = null;
SiteMapNode currentNode = SiteMap.CurrentNode;
 
var pageNode = currentNode as PageSiteNode;
 
 
while (pageNode == null) //Debug test by entering an infinite loop
      pageNode = SiteMapBase.GetActualCurrentNode();
 
//if currentNode is found, the rest of the code should function as per normal.
 if (item.Item is WrapperObject && ((WrapperObject)item.Item).WrappedObject != null)
 
      node = (PageNode)((WrapperObject)item.Item).WrappedObject;
else
      node = ((PageNode)item.Item);
if (node.Page != null && node.Page.Status == Telerik.Sitefinity.GenericContent.Model.ContentLifecycleStatus.Live)
       while (true)
        
             node = node.Parent; //gets the nodes parent information.
                         
              //if criteria is met the page will be filtered out towards it's specifications.
              if(node.Title.Equals(pageNode.Title,StringComparison.InvariantCultureIgnoreCase))
              
                  //filtered results

and when i put in the code for the infinite loop the re-indexing will never find the actual current node. 
The error it gives me when i run says "Object Reference with no Instance of Object"
And here is the Error Log

Hello,

First, let me explain some basics about the search functionality.
The publishing system, that uses so called pipes, only gathers the information and stores it in the search index (for example). Then when the user searches for this information (using the SearchResults widget for example), the results are extracted and shown (the information is already stored - all of it, not just the results).
When you click reindex, or you publish a page, it is absolutely normal that the current node is null. After all you are not even in the frontend.
I believe you are trying to see if the page that the user is on is a parent of the page that will be shown in the results. I think you have another ticket oppened with the same problem.
Lets move the discussion there, or do you think this thread should still be oppened for some reason?

Regards,
Bonny
