Object reference not set to an instance of an object.

After uninstalling, I got my root node back, but it leaves some uBlogsy tabs on the root node.

[NullReferenceException: Object reference not set to an instance of an object.] uBlogsy.Web.usercontrols.uBlogsy.dashboard.Admin.OnLoad(EventArgs e) +366

Hi Richard

That bug is really strange. I cannot replicate it.

I assume you're on Umbraco 4.7

Do you have any other starter kits installed?

Or any other tabs before installing the package?

Are there any nodes published before you installed the package?

Hi,

I am on 4.7.0 , only packages installed are: ImageGen, FamFamFam icons, Twitter for Umbraco

I have no starter kit, it's a fresh install of umbraco and buildup from the ground.

There was already content made and published. All running local on my dev machine btw.

Not sure what's happening and I am not able to debug it without source or pdb's

In Dashboard.config I have multiple tabs for BLog Comments & RSS Import tool, that might be the problem...

When I uncomment Blog Comments, than the tabs work again. RSS Import tab seems to work also.

I've been having this problem as well since the RSS import tool. I'd not raised it because I figured it was my sandpit environment but I've just set up a lovely fresh new site and the same issue occurs.

As for uninstalling I understood this to be a umbraco issue, rather than an issue with this package.

@Richard where is Blog Comments commented?

Ah nm, seems to be this in dashboard.config:

<tab caption="Blog Comments">
      <control addPanel="true">/usercontrols/uBlogsy/dashboard/Admin.ascx</control>
    </tab>

Commenting this out allows the to load the content root node BUT I get an error when trying to use the RSS import tool (not previsouly tested). I am using v1.31

Yes , same here when using RSS import..

This is really strange.

I've installed those 3 packages that you have Richard but cannot replicate the issue.

I might need some help debugging this. Below is what happens when the comments are displayed:

        protected void LoadComments()
        {
            Comments = new List<Document>();

            // get id root of blog
            Document blogFolder = DocumentHelper.GetDocumentByAlias("uBlogsyFolderBlog");
            if (blogFolder == null)
            {
                // hmm...the blog page was not there.
                return;
            }

            // iterate through year folders of the blog folder
            foreach (Document yearFolder in blogFolder.Children)
            {
                // iterate through year folders of the blog folder
                foreach (Document childDoc in yearFolder.Children)
                {
                    if (childDoc.ContentType.Alias == "uBlogsyFolderMonth")
                    {
                        // this year has month folders
                        foreach (Document post in childDoc.Children)
                        {
                            GetUnpublishedComments(post);
                        }
                    }
                    else
                    {
                        // this year has posts - but possibly months too
                        GetUnpublishedComments(childDoc);
                    }
                }
            }
        }

        /// This is a recursive method to get a document by it's alias.
        public static Document GetDocumentByAlias(string alias)
        {
            IEnumerable docs = Document.GetRootDocuments();

            foreach (Document d in docs)
            {
                var res = GetDocumentByAlias(d, alias);
                if (res.ContentType.Alias == alias)
                {
                    return res;
                }
            }

            return null;
        }

        private static Document GetDocumentByAlias(Document d, string alias)
        {
            if (d.ContentType.Alias == alias)

            {

            }
            return null; // not found but this should not be the case
        } 

        /// Gets unpublished comments from the post

            if (commentsFolder != null)
            {
                // get all comments from comments folder which are not published
                Comments.AddRange(commentsFolder.Children.Where(x => !x.Published));

        }

is working on a reply...
