I recently came across an interesting problem while working on an Infopath form. As part of the submission process, I needed to remove all the permissions from my new document. This seemed easy to do using by calling Item.BreakRoleInheritence = true and then removing all the existing permissions from the item.
When I published my form, I found that my approach generated an error: An exception of type ‘System.UnauthorizedAccessException’ occurred in Microsoft.SharePoint.dll but was not handled in user code. Additional information: Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))
After a bit of searching, I found this article: http://social.msdn.microsoft.com/Forums/en-US/sharepointdevelopment/thread/c3d2b304-7fcc-40d2-86ce-61d9b21b03d7 Look for the reply made by Kjetil Gullen on July 27.
