Integration build 0409.  Not sure if it happens on windows as well.  Steps:

- File -> New -> Project
- Plugin-in Development -> Plugin-in Project, Next
- enter a Project name like 'Abc', Next
- Next, to skip this page
- select 'Create new plugin using code gen wizard' radio
- select 'plug-in with multi-page editor' from list, Next
- Finish, get the attached exception

*sigh*.  My IE isn't able to display my attachment.  I'm not sure if others 
will have the same problem, so I'll paste it below just in case:

A must fix
Comment 4 Dejan Glozic CLA 2002-04-17 23:23:55 EDT 
Some fields in the template pages were initialized late (when page was made 
visible). However, since wizard can be finished at any time (without ever 
showing some pages), these fields were never initialized. Added a call to 
initialize all option fields before executing the template to cover this 
situation.
