Null reference error on getting value of Document type fields
I have just installed version 7.4.3 and installed Ublogsy on it , After the installation i just published the site . the home page works fine but when i try to preview the blog "Test Title" from the sample added by umbraco ublogsy installation, i get the following error. I have not changed any code from templates or partials. screenshots are
Could it be that your uBlogsyAuthorName haven't got a value? If that's the case, you're calling .Trim() in a null object which throws the null pointer exception you're getting.
Perhaps try use this, which checks if the property actually has got a value, before attempting to use it:
string name = a.HasValue("uBlogsyAuthorName") ? a.GetPropertyValue<string>("uBlogsyAuthorName").Trim() : string.Empty;
as you can see in second screen shot i have created an author by the name "Adeel". i also double checked it. Yeah i know this will ressolve my error for the time being but why its not picking up the author name?
I have used uBlogsy before and it caused some very annoying issues (most especially with uCommentsy). It also hasn't been updated in over a year. Have you considered Articulate?: https://our.umbraco.org/projects/starter-kits/articulate/

Hope that helps. If not, please let me know :-)

Hi Muhammad,
Yes, I'm aware that the author node is created, but still, does the property "uBlogsyAuthorName" have a value? :-)
And further: have you selected Adeel as the author of the post you're viewing?
Yes sir i have entered the uBlogsyAuthorName value. actually "Author Name" is the Name of the field, On mouse hover i get the alias.
Hi Muhammad,
I've now installed uBlogsy on a fresh Umbraco 7.4.3 and can definitely reproduce the exception that you're facing.
The exception is thrown on the method
GetPropertyValue<T>(string propertyTypeAlias)simply because a reference is missing.This is fixed by added the following references:
to the following views:
This should fix the issue :-)
thanks mate!!!
