http://blogs.msdn.com/jannemattila/archive/2007/02/08/moss-and-eventhandler-deployment-with-features-cannot-insert-the-value-null-into-column.aspxI posted earlier about my nasty experiences with site column deployment. This time I was working with eventhandlers and had interesting error message that I thought I'd share to you. I had created a pretty simple eventhandler and it was working fine.en-USCommunityServer 2.1 SP1 (Build: 61025.2)http://blogs.msdn.com/jannemattila/archive/2007/02/08/moss-and-eventhandler-deployment-with-features-cannot-insert-the-value-null-into-column.aspx#4070155Thu, 26 Jul 2007 23:07:16 GMT91d46819-8472-40ad-a661-2c78acb4018c:4070155Mark Kamoski<p>Thank you VERY much for this tip. As far as &quot;why on God's green earth SharePoint cannot handle a standard comment in an XML file&quot;, who the heck knows. It is making my ears bleed to hear this (yet more) bad news about SharePoint. Microsoft really, really, really should avoid trying to make their products &quot;fancy&quot; until AFTER then get the basic stuff working. I love SharePoint in many ways, but ug, come on guys and gals. Get the basic stuff done first. Thanks again. -- Mark</p> http://blogs.msdn.com/jannemattila/archive/2007/02/08/moss-and-eventhandler-deployment-with-features-cannot-insert-the-value-null-into-column.aspx#4855469Mon, 10 Sep 2007 22:03:43 GMT91d46819-8472-40ad-a661-2c78acb4018c:4855469Rita Girman<p>Thank you, thank you, thank you! &nbsp;Drove myself batty trying to get my simple event feature to activate. &nbsp;Removed all comments from Elements.xml and viola!...activation done. &nbsp;Curses, Microsoft!</p> http://blogs.msdn.com/jannemattila/archive/2007/02/08/moss-and-eventhandler-deployment-with-features-cannot-insert-the-value-null-into-column.aspx#5470978Tue, 16 Oct 2007 16:32:25 GMT91d46819-8472-40ad-a661-2c78acb4018c:5470978Brinkie<p>Wow, I would have never found this without your post...

I would never of thought that commented code would have caused my problems! My feature was working fine. My error occured when I wanted to create a new document library. I then got this error 'Unknown Error'. I found the same error that you have in the logs file and then found this article. After removing my commeneted code my error has gone! Thanks again!</p> http://blogs.msdn.com/jannemattila/archive/2007/02/08/moss-and-eventhandler-deployment-with-features-cannot-insert-the-value-null-into-column.aspx#8760672Mon, 21 Jul 2008 09:45:19 GMT91d46819-8472-40ad-a661-2c78acb4018c:8760672Log0<p>Nasty enough, thanks for the help.
