Question 1
For what use is the !worksite created. I though it was a template that was used in one of the tools.
Question 2
The worksite set-up tool has two wizards: course and project. With the configuration item 'Site types' we can add a type to be created and it shows up as an option in the first step of the wizard for creating a new site. This option however doesn't work. How can you add another wizard to worksite set-up tool.
Answers
!worksite is not used during site creation process neither in Admin Sites tool nor Worksite Setup tool. It merely serves as a template which you can copy/save as a new site in Admin sites tool.
In Sakai 1.5, if a new site type is added, a corresponding NEWTYPE_categories.xml file needs to be added to sakai-chef-tool>src>reg folder, which defines the tool set for this type of site. Please see the existing project_categories.xml for example.
