Error publishing/deleting content from previously working install
Running 4.7.1 on IIS7 we've suddenly started getting an "Object reference not set to an instance of an object" error when publishing (at umbraco.cms.businesslogic.web.Document.ToXml). This site has been working fine until today. The only change has been the addition of a couple of new document types "News List" and "News Item".
The stack trace is below. We've tried deleting the umbraco.config file and that doesn't get recreated which then made us think it was a user permissions error but the permissions on the folder are right. What's really interesting is we can't delete the page either (we get the same object reference not set to an instance of an object).
Does anyone have any ideas on what might be causing it?
Thanks
Tim

All I can think off is that your xml is malformed. Deleting umbraco.config should be first step, then browse /umbraco/dialogs/republish.aspx?xml=true and see what happens?
@Ian: Thanks I thought you might be onto something there but sadly that's not helped. There are properties on the parent doc types so there are input editors.
@Anthony: No ghosts sadly but good shout. We've deleted them and now none of the site publishes so I suspect it's not an issue with the data now...
@Dirk: That just reports success irritatingly, didn't think to hit it directly that's a good shout
In an attempt to resolve this we've spun up another install and oddly it will publish the site -but what's really bizarre is the perms are the same. I think something odd is going on with the permisisons somewhere.
Thanks all, we finally got to the bottom of the issue; it turns out one of the document types had a - in it's alias which broke the XML generation, turns out, relising the error of his ways, the dev renamed the document type's alias so it was hidden.
All good, lesson for today is don't include non-alphanumeric chars in the document type aliases!
Yes, our parent document types have -'s in the name but it was more that the alias had a - in it. Umbraco doesn't stip these when creating the XML and so, breaks.
I solved the problem already!. It turns out that this error was the alias of DocumentTypes. Ex: "Contact Us", the alias would be "ContactUs" worst I had as "Contact-Us", and that fucking script was the problem. What if someday encounter this you know!. Greetings friends!

Tim,
You tried restarting the app pool?

Sadly we have Ismail yep, even tried creating a new one :(
One other thing that might be worth noting is that there are no properties on the document type (I've seen the naming conventions conflict before).
The deletion is what's really bugging me...
Is it worth adding some properties to the document type?
Something in the back of my mind says I have seen this before, but I can't remember where or when.
I guess otherwise, it's get the umbraco source, and attach the debugger, see if you can step through the stack trace and find what hasn't been set..
Have you looked for ghost nodes?

Delete the new doc types or change the aliases and see if the problem remains.

I'll update if we get further.
Did you delete or add any templates?
Doc types refer to templates and a missing one can cause a crash.

So the doctype was created with a "-", then renamed?

Thank you!. In reply I have solved the problem!
