Hi,

This is weird. There will be a call to umbraco.library.IsProtected indeed but only when item is of type content. But Media protect uses HTTPContext internally also so that might be the issue. So you are saying that you can't use HTTPContext when indexing using Examine?

Thanks,

Richard

Making any call to the MediaProtect API is causing a null reference exception when calling IsProtected against a media item within the Examine GatheringNodeData event. We need to add an indexing property to show if a media item is protected or not. Perhaps there is another way to do this?

@Richard could we make a database call directly?

Hi Mark,

Will add this to my list to implement also(will not be in the next few days/weeks sorry). I like the way you want to solve this. Most customers I have use the IsProtected method when rendering the overview. This is because you can change the protection without saving the node. Also possible for you to use maybe?

But protected data is stored in app_data/mediaaccess.config file. Also possible to use that, but not ideal I think.

Best,

Richard

Hi Richard,

That's a shame. I was following this post which said it was possible to do what I wanted to do with MediaProtect. I'll have to come up with a work around as I can't wait, unfortunately. Anyway, thanks for coming back to me.

Mark

Hi Mark,

Did you try that exact method also in that blogpost?

Thanks,

Richard

Hi Richard,

The method MediaProtect.Library.AllowedGroups() isn't there. But there is a static MediaProtect.Library.Library.AllowedGroups() method, which is the one I'm trying to use. The method gives the same error as MediaProtect.Library.Library.IsProtected():

System.NullReferenceException was unhandled
  HResult=-2147467261
  Message=Object reference not set to an instance of an object.
  Source=MediaProtect
  StackTrace:
       at MediaProtect.Configuration.Config.get_MediaAccessFile()
       at .()
       at .(Int32 )
       at MediaProtect.Access.MediaAccess.AllowedGroups(Int32 mediaId, String path)
  InnerException: 

I assume this is the same problem. Is there another way to call those methods? Maybe an instance method rather than static?

Thanks,
Mark

Strangely, it looks like umbraco.cms.businesslogic.web.Access.IsProtected() method does access httpcontext, so maybe there is something else going on. Although maybe the umbraco method isn't hitting httpcontext because it's accessing a cache...

Hi Mark,

That's the method to use Mediaprotect.Libary is used in XSLT which came before razor. But the HTTPContext is in another method that is used by the library. I think I can rid of the HTTPContext in my own library but it makes calls to Umbraco also.

But still weird that HTTPContext is throwing exceptions in this index methods.

Maybe it isn't httpcontext. Are you able to reproduce the issue?

Added toExamineIndex.config:

 <IndexSet SetName="SiteSearchIndexSet" IndexPath="~/App_Data/TEMP/ExamineIndexes/SiteSearch/" />

Added to ExamineSettings.config:

<add name="SiteSearchIndexer" type="UmbracoExamine.UmbracoContentIndexer, UmbracoExamine"
             supportUnpublished="false"
             supportProtected="true"
             analyzer="Lucene.Net.Analysis.Standard.StandardAnalyzer, Lucene.Net"/>

 <add name="SiteSearchSearcher" type="UmbracoExamine.UmbracoExamineSearcher, UmbracoExamine" />

Added this class (uncomment the commented line, also add reference to MediaProtect.dll):

using System;

using System.Linq;
using System.Web;
using Umbraco.Core;
using Examine;
using umbraco.cms.businesslogic.web;

        }

        void ExamineEvents_GatheringNodeData(object sender, IndexingNodeDataEventArgs e)
        {
            if (e.IndexType == "content")
            {
                if (Access.IsProtected(int.Parse(e.Node.Attribute("id").Value), e.Node.Attribute("path").Value))

                }
            }
            else if (e.IndexType == "media")

        public void OnApplicationStarted(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext)

        {
            
        }
    }
}

I'd like to make sure I'm not doing something wrong...

Hi Mark,

I'll setup a dev environment to reproduce thanks for the detailed instructions.

Thanks,

Richard

Hi Mark when trying to compile I get the following error

Error 1 No overload for 'ExamineEvents_GatheringNodeData' matches delegate 'System.EventHandler' f:\temp\examinetest\MediaProtectExamine\MediaProtectExamine\ExamineEvents.cs 15 103 MediaProtectExamine

This error is in the constructor

  public ExamineEvents()
        {
            ExamineManager.Instance.IndexProviderCollection["SiteSearchIndexer"].GatheringNodeData += new EventHandler(ExamineEvents_GatheringNodeData);
        }

Any ideas? Also possible to mail me [email protected]

Thanks,

Richard

@Richard - thanks for all your help. Problem solved. I'll mark your answer. I'll also order a Media Protect license for this project shortly.

Mark

Hi Mark,

Thanks for both!

Best,

Richard

Hi Richard,

Is v1.5.1 available yet? We are seeing the same issue in our GatheringNodeData event, in a call to MediaProtect.Library.Library.IsProtected.

Thanks,

Mike

Hi Michael,

I thought it was released already but it isn't sorry. I will release it next week. If you need the package before send me an email please [email protected] and I'll send it.

Best,

Richard

Hi

Im having the same problem, but im running MediaProtect on version 2.0

I get: The value should not be null. Parametername: httpContext

On this piece of code inside the GatheringNodeData event:

bool isProtected = Library.IsProtected(node.Id, node.Path);

Is there anything im missing? Or is this broken again?

Best regards

Nils

Hi,

Did you upgrade from a previous version? Mediaprotect V2 just instatiates the concrete object without loading dll's so I am curious what is causing this?

Best,

Richard

Hello,

I'm having this same issue on Umbraco 7.65 and MediaProtect 2.0.0.
I'm calling AllowedGroups to add properties to my Examine document index.
I noticed that after I lauch the site, I can save a file as many times as I want and it's ok. When I try to save another file, I get the error. It's not file related, tested with different files. The error occurs always when I rebuild the index, even on the first file (iteration).

System.ArgumentNullException occurred
  HResult=0x80004003
  Message=Value cannot be null.
Parameter name: httpContext

Mediaprotect needs HTTPContext which is not available in Examine. You can request acces rights at runtime.

Hope this helps,

Richard

Hi,

That helped!

I was able to instantiate the HttpContext with a call to UmbracoContext.EnsureContext(helper.UmbracoContext.HttpContext, ... )
Although, it would be much cleaner if I could pass helper.UmbracoContext.HttpContext as a parameter to an overload of your functions. Would that be possible?

Thanks,
Mário
