Can't get Calendar to work

I tried to create a calendar application. Didn’t customize anything. Picked the 3 required fields. When I generate the application I get this error:

Fatal error: Call to a member function GetTag() on a non-object in C:\Program Files (x86)\NetMake\v71\wwwroot
ew_scriptcase\devel\class\generator
mFontePHPForm.class.php on line 12347

What can I be doing wrong?

Thanks

Ted

Have you tried to setup with the full number of fields? Could be a bug, but with the full number of fields it works.
