Viewing Document Type Error

Hello all,

Setup:
Version: Umbraco 461 (web root - not virtual directory)
Package: KIOAK Standard Site
Server: W2K3 / IIS6 / SQL2008 Express / ASPNET 4.0

Issue:
I am a newbie, please bare with me. I created a couple of document types to be used in a macro. Then created some contents for them. Next I created the XSLT macro. Then I put the macro inside a page template. Everything went OK. I did not see any erorr what so ever. But when I tried to go back and view the document type to make some additions, I received an exception. In fact, every document type now is throwing exception when viewing. Detailed exception below:

Object reference not set to an instance of an object. body {font-family:"Verdana";font-weight:normal;font-size: .7em;color:black;} p {font-family:"Verdana";font-weight:normal;color:black;margin-top: -5px} b {font-family:"Verdana";font-weight:bold;color:black;margin-top: -5px} H1 { font-family:"Verdana";font-weight:normal;font-size:18pt;color:red } H2 { font-family:"Verdana";font-weight:normal;font-size:14pt;color:maroon } pre {font-family:"Lucida Console";font-size: .9em} .marker {font-weight: bold; color: black;text-decoration: none;} .version {color: gray;} .error {margin-bottom: 10px;} .expandable { text-decoration:underline; font-weight:bold; color:navy; cursor:hand; }

The site is still running fine, though. I am now really not sure how to proceed. Thank you in advance for your kind help.

[UPDATE]

Hello all,

I found similar issues from these posts -

http://our.umbraco.org/forum/core/general/6977-Error-when-trying-to-view-Document-Types-in-Umbraco
http://our.umbraco.org/forum/getting-started/installing-umbraco/6226-Error-Document-Types
http://our.umbraco.org/forum/templating/templates-and-document-types/13298-error-viewing-document-types-

... and probably a few more but I'm too lazy to search.

One post solved it by rebooting his server. Another solved it by reinstalling ASPNET or iisreset. Very drastic. Whatever the issue is, it obviously happened enough to probably be a bug.

I too have resolved it. However, only by restarting both SQL service from SQL Config Mngr and the website from IIS Mngr, in that order.

Hope this help others with similar issue.

Hi Mosabusan

Glad to hear you got this issue solved. Have you checked to see if there has actually been filed a bug report on this on codeplex? And do you have any idea on how to recreate the issue? Otherwise I guess the core team will have a hard time figuring out what is the cause..

/Jan

Hi Jan,

Thanks for the reply. To answer your questions:

No, I have not check if there is a bug report for similar issue at codeplex. I will check later.

And I have not tried to purposely recreate the issue. However, I did delete the document type that I created last prior to the issue and rebuild it without issue. I had since then created more document types and have viewed and edited them many times, without any issue also.

It is probably one of those weird issues that only happpen when the moon, the sun and other celestial bodies are aligned just right. :)

I will update this post if this happens again. Thank you.
