Say you’re working with Visual Studio to develop a SharePoint 2010 solution, using your own Content Type. The XML-based definition of Site Columns and Content Types often requires you to use the values “FALSE” and “TRUE” for boolean attributes like “Sealed”, “Required”, etc.
So when you define a boolean Site Column, you can use those values “FALSE” and “TRUE” to define the default value for the column/field, right?
No, you can’t. For “TRUE”, use
<Default>1</Default>
That’s a great way to make newbies lose their time (and more), Microsoft!
