Last month I got some error messages after creating a customized onet.xml and content types in SharePoint. One of the error messages was: A duplicate name "Item" was found. After taking a look into the SharePoint log files I found more details:
| w3wp.exe (0x0474) | 0x0D34 | Windows SharePoint Services | General | 8l35 | High | Failed to activate site-collection-scoped features for template 'TEMPLATE#0' in site collection 'http://moss2007'. |
| w3wp.exe (0x0474) | 0x0D34 | Windows SharePoint Services | General | 72h9 | High | Failed to apply template "TEMPLATE#0" to web at URL http://moss2007. |
| w3wp.exe (0x0474) | 0x0D34 | Windows SharePoint Services | General | 72k2 | High | Failed to apply template "TEMPLATE#0" to web at URL http://moss2007, error Provisioning did not succeed. Details: Failed to create the 'Cache Profiles' list. OriginalException: A duplicate name "Item" was found. 0x8107058a |
I tried to create a website based on my custom ont.xml and my custom content types. The reason for this error message was a spelling error in my custom content type:
<ContentType ID="0x010100............08}"
After removing the bracket at the end the site creation process was successful.
