Object reference not set to an instance of an object

General

I am using Umbraco v6.1.6 for a quiet big project.

It's all working fine. But there is a folder of Retailer with 20,30 retailers in it. I try to open them in Umbraco to make some changes and i get this error:

Server Error in '/' Application.

Object reference not set to an instance of an object.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.

All of the retailers open in the front end, no problem, but it's broken in CMS part.

The interesting part is they open in the test server, but they don't open locally. I really don't know what to do. We have to make the changes locally along other changes and then upload the database and the code for the client in the test area to see. it means i cannot make the changes in the test area, because it will overwritten later by the local version.

anybody knows what's the reason?

Many Thanks in advance, Mitra

I finally got the answer and resolved this.

One of the document types in the page was using 'limit char' package. The package was broken locally(i'm not sure how?) so i was getting error when i was trying to open the cms page in umbraco.

I though to leave this message here for those who might/will have similar problem.
