I am trying to create a KPI list win SharePoint 2007 SP2. The AllItems.aspx page seems to work correctly, but loading the KPIListViewPage.aspx page gives "An unexpected error has occurred".
Opening the page in Designer gives this error:
"Error Creating Control - toolBarTbl
The WebPart could not be deserialized from the markup"
Deleting the web part makes the page load, but without the toolbar.
In SP1, you can create KPI lists without an error, yet when you open the page in SharePoint Designer, you still get the same error as above with the web part. SP1 just seems to ignore it and carry on working anyway, including the toolbar.
I've googled this problem, and it seems to have happened to a few people, but no resolution. Any ideas?
