Tag "tableView" contains invalid attribute values.

Hi,

I'm working my way through the BSP extension examples in the WAS programming book, and keep getting the following error every time I use the tableView extension:

<HTMLB:tableView>: (Attribute=columnCount) The attribute does not exist. (Compile time validation error).

Tag "tableView" contains invalid attribute values.

The error occurs even when I try to activate one of the built-in example BSP applications in the miniBSP. Is it my installation that lacks something, or is this a known error?

I'm on XP Pro, Explorer 6, miniBSP (6.20)...
